In 2019,Advanced Synthesis & Catalysis included an article by Zheng, Xixi; Wan, Jie-Ping. Recommanded Product: 924-99-2. The article was titled 《The C=C Bond Decomposition Initiated by Enamine-Azide Cycloaddition for Catalyst- and Additive-Free Synthesis of N-Sulfonyl Amidines》. The information in the text is summarized as follows:
The chemo-selective synthesis of N-sulfonyl amidines is realized via the decomposition of the enamine C=C bond of enaminoesters through an in situ generated triazoline intermediate. Control experiments prove that the electron withdrawing ester group in the enamine component is crucial in inducing the chemo-selective formation of amidines. The method is featured with high efficiency and sustainability by employing pure water as medium without requiring any catalyst or additive.Ethyl 3-(dimethylamino)acrylate(cas: 924-99-2Recommanded Product: 924-99-2) was used in this study.
Ethyl 3-(dimethylamino)acrylate(cas: 924-99-2) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.Recommanded Product: 924-99-2
