The synthesis of 1,4-dihydroquinoline-3-carboxylates from 2-benzoyl-3-[2-(dialkylamino)aryl]acrylates
摘要
A method for the synthesis of 1,4-dihydroquinoline-3-carbonyl compounds from 2-benzoyl-3-[2-(dialkylamino)aryl]acrylates via the sequence of 1,5-hydride shift, dealkylation, and cyclization processes was proposed. The reaction products contained a push-pull enamine fragment.
