Substituted 1,2-dihydroquinolines have been synthesised from substituted anilines and methyl pyruvate using catalytic amounts of commercially available Bi(OTf)3 as a catalyst under microwave-assisted conditions. This method is simple, easy to work up, inexpensive, with a broad substrate scope and short reaction times. The reaction provides 1,2-dihydroquinolines (19 examples) in good yields (34-97%
在微波辅助条件下,使用催化量的市售 Bi(OTf)3 作为催化剂,由取代的苯胺和丙酮酸甲酯合成了取代的 1,2-二氢喹啉。该方法简单、易于操作、价格低廉、底物范围广、反应时间短。该反应以良好的产率(34-97% 的产率)提供了 1,2-二氢喹啉(19 个实施例)。
