Bromodimethylsulfonium bromide catalyzes Mannich-type reactions of a variety of aldimines, generated in situ from aldehydes and anilines, with enolizable ketones or diethyl malonate in three-component reactions to afford the corresponding β-amino carbonyl compounds. The salient features of this protocol are: shorter reaction times, simplicity of the procedure, good to excellent yields, avoidance of
溴化二甲基锍溴化物催化由醛和苯胺原位生成的各种醛亚胺的曼尼希型反应,与可烯醇化的酮或丙二酸二乙酯在三组分反应中得到相应的 β-氨基羰基化合物。该方案的显着特点是:反应时间更短、程序简单、产率好到极好、避免了水处理和柱色谱分离,以及高立体选择性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim , 德国, 2008)
