Nigrifactin analogues: Synthesis of some hetero‐aromatic polyenes via the Horner reaction

Abstract
Some all‐trans 1,3,5‐heptatrienyl and 6‐ethoxycarbonyl‐1,3,5‐hexatrienyl substituted heterocyclic compounds have been synthesized, employing Horner reactions of heterocyclic aldehydes or heterocyclic methylphosphonates.
