X, wherein X is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, alkylaryl, substituted alkylaryl, heterocycle, or substituted heterocycle. Compounds of group A may be used for treating various diseases or disorders, such as cancer.
pre-equilibrium in the formation of iminodiazonium (ID) ion and that the N2 liberation from the ID ion is rate-determining. Under high azide concentration conditions, where the effective reactant is the ID ion, the reaction gave a linear Hammett plot with a ρ value of −0.50. The observed substituent effects on the rate and the product selectivity imply that path bifurcation on the way from the rate-determining
A Single Lipase-Catalysed One-Pot Protocol Combining Aminolysis Resolution and Aza-Michael Addition: An Easy and Efficient Way to Synthesise β-Amino Acid Esters
was developed to obtain chiral β-amino acid esters with lipase B from Candida antarctica (CAL-B) as the only catalyst. This method is conducted under mild reaction conditions and is very easy to handle. After a series of detailed optimization studies, ten racemic aromatic or aliphatic amines were subjected to this one-pot procedure, and twelve chiral β-amino acid esters and ten chiral amides were successfully
开发了一种结合 aza-Michael 加成和氨解拆分的新型一锅法,以来自南极念珠菌 (CAL-B) 的脂肪酶 B 作为唯一催化剂获得手性 β-氨基酸酯。该方法在温和的反应条件下进行,非常容易操作。经过一系列详细的优化研究,10 种外消旋芳香族或脂肪族胺经过此一锅法处理,成功合成了 12 种手性 β-氨基酸酯和 10 种手性酰胺,其 ee 值在理论产率下具有优异的值。放大程序也没有明显降低反应速率或对映选择性,这使得该方法适用于手性 β-氨基酸酯的大规模生产。

A simple and efficient Mn-catalyzed acylation of amines is achieved using both acyl and alkoxy functions of unactivated esters with the liberation of molecular hydrogen as a sole byproduct. The present protocol provides an atom-economical and sustainable route for the synthesis of amides from esters by employing an earth-abundant manganese salt and inexpensive phosphine-free tridentate ligand.
