The anionic phospho-Fries rearrangement of phosphoric acid (3,5-di-isopropoxy)phenyl ester diethyl ester (11) gave rise to (2-hydroxy-4,6-di-isopropoxy-phenyl)phosphonic acid diethyl ester (12) in excellent yield. The phenol functionality of 12 was converted to the corresponding triflate which was coupled with vinyltributylstannane, under Stille conditions, to give a styrene. This molecule is intended to serve as the aromatic fragment in the synthesis of a phosphorus-based transition-state analogue for the hydrolysis of the S-(-)-zearalenone lactone.
