CHIMIE DES FRAGRANCES, PARTIE II: SYNTHESE DE LA γ-IONONE ET DES CIS- ET TRANS-γ-IRONES

Leyendecker, Francois,Comte, Marie-Therese

, p. 85 - 92 (2007/10/02)

A new convergent synthesis of γ-ionone and cis- and trans-γ-irones is described.A tandem 1,4-addition functionnalisation reaction and a chemo- and regioselective olefination reaction are the key steps.A two dimensional NMR study allows the determination of the favoured configuration of one intermediate.
