Procedure

The procedure followed is the same as that described in Example 11 substituting the starting material prepared in Example 28, 6,6-dichloro-2-(3-[(1,1-dimethylethyl)dimethylsiloxy]pent-1-yl)bicyclo[3.2.0]-heptan-7-one{7,7-dichloro-4-[3,[[(1,1-dimethylethyl)dimethylsilyl]oxy]pentyl]bicyclo[3.2.0]heptan-6-one} and isomers (2.4 g, 6.1 mmoles), glacial acetic acid (17 ml), and zinc powder (5 g). The crude produce is chromatographed on silica gel and subsequently kugelrohred under vacuum leaving a clear, colorless oil (1.0 g, 4.8 mmoles).
