Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. 99769-19-4, formula is C8H9BO4, Name is 3-(Methoxycarbonyl)phenylboronic acid. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. SDS of cas: 99769-19-4.
Jiang, Xunjin;Zeng, Zhixiong;Hua, Yuhui;Xu, Beibei;Shen, Yang;Xiong, Jing;Qiu, Huijuan;Wu, Yifan;Hu, Tianhui;Zhang, Yandong research published 《 Merging C-H Vinylation with Switchable 6π-Electrocyclizations for Divergent Heterocycle Synthesis》, the research content is summarized as follows. Pyridinium-containing polyheterocycles exhibit distinctive biol. properties and interesting electrochem. and optical properties and thus are widely used as drugs, functional materials, and photocatalysts. Here, we describe a unified two-step strategy by merging Rh-catalyzed C-H vinylation with two switchable electrocyclizations, including aza-6π-electrocyclization and all-carbon-6π-electrocyclization, for rapid and divergent access to dihydropyridoisoquinoliniums and dihydrobenzoquinolines. Through computation, the high selectivity of aza-electrocyclization in the presence of an appropriate “HCl” source under either thermal conditions or photochem. conditions is shown to result from the favorable kinetics and symmetries of frontier orbitals. We further demonstrated the value of this protocol by the synthesis of several complex pyridinium-containing polyheterocycles, including the two alkaloids berberine and chelerythrine.
