Abstract

Abstract 1, 6-Dibromohexa-1, 3, 5-triene, previously described by us and easily obtained from 5-bromopenta-2, 4-dienal by condensation with bromomethylene triphenylphosphorane, is a versatile precursor for the synthesis of conjugated 1, 3, 5-trienic derivatives of controlled configuration. In this paper, we describe the stereocontrolled synthesis of E, E, Z, E, E, E and Z, E, Z isomers of α-bromo-ω-substituted-1, 3, 5- ...
