89% | General procedure: The starting material (2 mmol) was added to a sealed tube holding 20 mL of a 1:1 mixture of acetonitrile/water and KOH (40 mmol), whichwas cooled using an ice bath. The mixture was vigorously mixed for 15min and then phosphonate 1 (4 mmol) was added to the mixture in oneportion, and mixing and cooling was maintained for an additional 15 -60 min, followed by ~30 min - 2.5 h at r.t. The reaction mixture wasthen diluted with ether (10 mL) and the organic phase separated. Thewater phase was further washed with ether (10 mL). The combinedorganic phase was dried over anhydrous Na2SO4 and the solvent evaporatedto provide a crude product which was purified using columnchromatography on silica gel |
