Abstract: A convenient two step stereoselective synthesis of (E)-methyl O-alkylferulate 5a-c is described from vanillin 1. Reaction of vanillin 1 with allyl-, prenyl- or geranyl- bromide 2a-c has afforded alkyl ethers 3a-c which on reaction with phosphorane 4 , under microwave irradiation, gives (E)-methyl O-alkylferulates 5a-c in high yield. In an alternative approach vanillin 1 on reaction with phosphorane 4 provides (E)-methyl ferulate 6 which on reaction with the corresponding bromides 2a-c gives (E)-methyl O-alkylferulates 5a-c .
