Participants

Reaction Steps

To a stirred solution of aldehyde 13, (1 g, 2.9 mmol) in THF was added (methoxycarbonylmethylene)triphenylphosphorane, 2 g (6 mmol). The mixture was stirred at room temperature for 70 hours. The mixture was diluted with EtOAc and the organic phase was washed with 2M HCl, saturated NaHCO3 and brine, dried over MgSO4 and evaporated in vacuo. The crude unsaturated ester 14 was purified on silica to yield 1.2 g as a white solid (99%).
