Synthesis of highly functionalised linear pentacyclic compounds from Baylis-Hillman adduct of heteroaldehydes with azomethine ylides via [3+2] cycloaddition

Abstract

Montmorillonite K10 clay promoted one-pot synthesis of penta- and tetracyclic systems from Baylis-Hillman adduct of heteroaldehydes with azomethine ylides generated from ninhydrin and proline or sarcosine via [3+2] cycloaddition is reported.
