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