Facile synthesis of unknown 6,7-dihydrofuro[3,4-c]pyridines and 3,4-diaryloylpyridines from N-homopropargylic β-enaminones

Abstract

A simple methodology for the synthesis of bicyclic 6,7-dihydrofuro[3,4-c]pyridines is reported. The skeletal diversity of the synthesized heterobicyclic frame may present new nitrogen- and oxygen-based hybrid systems for medicinal chemistry.
