electron-withdrawing groups undergo rapid reactions with a variety of alcohols and secondary amines to afford the corresponding esters and amides, respectively, in high yields, when treated with NaCN or acetone cyanohydrin and base under ambient reaction conditions. In case of α,β-unsaturated aldehydes, simultaneous reduction of the CC bond along with esterification occurred to produce the saturated esters in high
当在环境反应条件下用NaCN或丙酮氰醇和碱处理时,具有吸电子基团的芳香醛与各种醇和仲胺快速反应,分别以高收率得到相应的酯和酰胺。在α,β-不饱和醛的情况下,同时发生CC键还原和酯化反应以高收率产生饱和酯。
