Trans-N-acyl-N-alkyl-1-amino-1,3-butadienes, trans-N-acyl-N-aryl-1-amino-1,3-butadienes and preparation thereof

Abstract

Trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are prepared by contacting a conjugated azomethine with a strong base in an inert organic solvent at sub-zero temperature and thereafter acylating the resulting product. The trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are useful as intermediates in the formation of substituted decahydro-quinolines, Pumiliotoxin C, and can also be used as the diene in Diels-Alder reactions or can be copolymerized with vinyl compounds.
