To date, the N‐alkylation of amides with alcohols has not been studied with non‐noble metal base heterogeneous catalyst. Herein, a range of amide was efficiently N‐alkylated with various alcohols using cheap and easy to handle Ni/SiO2‐Al2O3.
迄今为止,尚未使用非贵金属碱多相催化剂研究酰胺与醇的N-烷基化。在此,使用廉价且易于处理的Ni / SiO 2 -Al 2 O 3将各种酰胺有效地与各种醇进行N-烷基化。

unique catalytic properties, stability and enantioselectivity of the relatively unknown penicillin acylase from Alcaligenesfaecalis has been developed for the effective and enantioselective acylation of amines in aqueousmedium. In contrast to lipase-catalyzed acylations in organic solvents, the penicillin acylase-catalyzed acylation of amines in aqueous solution is a rapid and chemoselective process

carbene-based ruthenium(II) hydride complexes were developed for amidesynthesisfromalcohols and amines under base-free conditions. Diverse amides were synthesized in fair-to-excellent yields. In the case of secondary amines, where direct dehydrogenative amidation is not feasible, a catalytic amount of a base was required to promote the transamidation of esters, which are byproducts of alcohol dimerization
