2-Methoxy-1,3-dienes - Preparation via α-Methoxyallylphosphine Oxides using a One-pot Wittig-Horner Reaction

2-Methoxy-1,3-dienes bearing an aryl group at position 1 and/or 4 are readily available in a one-pot Wittig-Horner reaction using α-methoxyallylphosphine oxides (1a) or (1b).

REGIOCHEMISTRY OF REACTIONS OF α-ALKOXYALLYLPHOSPHINE OXIDE YLIDES WITH ELECTROPHILES.

Anions 4, derived from α-methoxyallylphosphine oxides 3, react with electrophiles in a highly regioselective fashion to give products of α-attack or γ-attack depending upon the substitution pattern of the ylid 4 and the nature of the electrophile.
