《A Specific Blend of Drakolide and Hydroxymethylpyrazines: An Unusual Pollinator Sexual Attractant Used by the Endangered Orchid Drakaea micrantha》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Bohman, Bjoern; Tan, Monica M. Y.; Phillips, Ryan D.; Scaffidi, Adrian; Sobolev, Alexandre N.; Moggach, Stephen A.; Flematti, Gavin R.; Peakall, Rod. Safety of Ethyl 2-methyl-3-oxobutanoate The article mentions the following:

Bioactive natural products underpin the intriguing pollination strategy used by sexually deceptive orchids. These compounds, which mimic the sex pheromones of the female insect, are emitted in particular blends to lure male insect pollinators of specific species. By combining methods from field biol., anal. chem., electrophysiol., crystallog., and organic synthesis, we report that an undescribed β-hydroxylactone, in combination with two specific hydroxymethylpyrazines, act as pollinator attractants in the rare hammer orchid Drakaea micrantha. This discovery represents an unusual case of chem. unrelated compounds being used together as a sexual attractant. Furthermore, this is the first example of the identification of pollinator attractants in an endangered orchid, enabling the use of chem. in orchid conservation. Our synthetic blend is now available to be used in pollinator surveys to locate suitable sites for plant conservation translocations.

《Chemo- and Enantioselective Oxidative α-Azidation of Carbonyl Compounds》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Uyanik, Muhammet; Sahara, Naoto; Tsukahara, Mayuko; Hattori, Yuhei; Ishihara, Kazuaki. Synthetic Route of C7H12O3 The article mentions the following:

The authors report high-performance I+/H2O2 catalysis for the oxidative or decarboxylative oxidative α-azidation of carbonyl compounds by using sodium azide under biphasic neutral phase-transfer conditions. To induce higher reactivity especially for the α-azidation of 1,3-dicarbonyl compounds, the authors designed a structurally compact isoindoline-derived quaternary ammonium iodide catalyst bearing electron-withdrawing groups. The nonproductive decomposition pathways of I+/H2O2 catalysis could be suppressed using a catalytic amount of a radical-trapping agent. This oxidative coupling tolerates a variety of functional groups and could be readily applied to the late-stage α-azidation of structurally diverse complex mols. Moreover, the authors achieved the enantioselective α-azidation of 1,3-dicarbonyl compounds as the first successful example of enantioselective intermol. oxidative coupling with a chiral hypoiodite catalyst.

Han, Jinlong; Yin, Yue; Xu, Duo; Wang, Hao; Yu, Shuang; Han, Dongyun; Niu, Yunxia; Xu, Runyu published an article in 2021. The article was titled 《Growth inhibition and oxidative damage of Microcystis aeruginosa induced by aqueous extract of different submerged macrophytes》, and you may find the article in Environmental Science and Pollution Research.Reference of Ethyl 2-methyl-3-oxobutanoate The information in the text is summarized as follows:

With the increasing eutrophication of the aquatic environments, cyanobacteria blooms caused certain damage to the animals and plants in the aquatic environments. In this experiment, two species were selected from six species of submerged macrophytes, the exptl. conditions were changed to achieve the best inhibitory effect on Microcystis aeruginosa, and oxidative damage anal. was carried out. The experiment results demonstrated that the inhibition rate of Vallisneria natans and Ceratophyllum demersum was nearly 100% at the concentration of 3 g/L after 15 days of anaerobic soaking extract In addition, the longer the soaking time of the two submerged macrophytes, the weaker the photosynthesis effect, and the lower the chlorophyll fluorescence parameters, the more obvious the inhibition effect on M. aeruginosa. Lipid peroxidation injury of M. aeruginosa could be reflected by malondialdehyde (MDA) concentration The MDA concentration in the exptl. group was significantly higher than the control group. Results showed that V. natans and C. demersum could induce oxidative damage in M. aeruginosa. It was also observed that the secondary metabolites produced by V. natans were mainly fatty acids (e.g., the oxidative acid was 6.92 w/%, and the successful acid was 9.85 w/%) which inhibited M. aeruginosa in gas chromatog.-mass spectrometry (GC-MS). The main secondary metabolites in C. demersum were hydroxyl acids (e.g., the 4-hydroxy-3-methoxyphenylacetic acid was 24.33 w/%), which could inhibit the algae through allelopathy. This study provided reference for submerged macrophytes to inhibit M. aeruginosa under different conditions. In the experiment, the researchers used Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Reference of Ethyl 2-methyl-3-oxobutanoate)

In 2022,Naikwadi, Dhanaji R.; Mehra, Sanjay; Ravi, Krishnan; Kumar, Arvind; Biradar, Ankush V. published an article in ACS Sustainable Chemistry & Engineering. The title of the article was 《Cellulose@PO3H: As an Efficient and Recyclable Ionic Liquid-Enabled Catalytic Greener Approach to One-Step Synthesis of Flavoring Ketones》.Application of 609-14-3 The author mentioned the following in the article:

Cellulose (CL) is widely available from the renewable biomaterial on the earth with a large number of hydroxyl functionalities on its surface. The appropriate modification of these functionalities results in the acidic and basic nature of the surface. In this work, the phosphoric group-functionalized CL ionic liquid (IL) has been successfully synthesized through phosphorylation of the CL surface. The phosphorus functionalization of CL was carried out in two steps; first, synthesis of IL (3, 5-lutidinium Me phosphate [Lut][(MeO)(H)PO2]), followed by phosphorylation of cellulose (CLP-IL). Subsequently, CLP-IL has been characterized by various physicochem. techniques. Significant changes in the activity were observed, with marginal changes in the structural and morphol. properties of the native CL. CLP-IL has been utilized to synthesize industrially important flavoring ketones (FKs) via one-step alkylation-decarboxylation of active methylene compounds with substituted benzyl alcs. and halides. The functionalized CL IL could be quickly recovered in water and recycled at least five times without losing the catalytic activity. The optimized protocol has been successfully employed for the synthesis of FKs with an excellent conversion of substituted benzyl carbons in the range (90-100%) with 70-90% isolated yield of desired market valuable products. Furthermore, the mechanism was established by identifying the intermediates by physicochem. methods.

《Cut and sew: benzofuran-ring-opening enabled cyclopentenone ring formation》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Wang, Kai; Jiang, Chenghao; Zhang, Zhenming; Han, Chunyu; Wang, Xuewei; Li, Yaping; Chen, Kaiting; Zhao, Junfeng. Application In Synthesis of Ethyl 2-methyl-3-oxobutanoate The article mentions the following:

A facile approach to the fully substituted cyclopentenones involving an unprecedented benzofuran-ring-opening has been described. For example, treatment of dienyl-substituted benzofurans I (R1 = H, 5-Me, 6-O2N, 5,6-benzo, etc.; R2 = CN, MeCO, EtO2C, MeSO2, etc.) with a catalytic amount of TMSOTf in nitromethane afforded the corresponding phenol-substituted indenones II in moderate to good yields and with good diastereoselectivity. The cleavage of a benzofuran endocyclic C2-O bond proceeded smoothly in the absence of any transition metal catalyst or highly reactive organometallic reagent. Such benzofuran-ring-opening is delicately incorporated into an acid-catalyzed cascade process, orchestrating a novel synthetic strategy for complex cyclopentenones. In the experiment, the researchers used many compounds, for example, Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Application In Synthesis of Ethyl 2-methyl-3-oxobutanoate)
