  Preparation of 3-Methylenesilacyclobutane and its Use in Organic Synthesis

  摘要：

  Treatment of 3-methylene-1,1-diphenylsilacyclobutane (1a) with dihalo-methyllithium provided ring expanded 2-halo-4-methylenesilacyclopentane. Heating a mixture of In and carbonyl compound such as phCHO or PHCOMe at reflux in 1,2-dichloroethane afforded S-methylene-1,1-diphenyl-2-oxa-1-silacyclohexane which was converted into 3-methylene-15-alkanediol monomethyl ether upon treatment with dimethyl acetal in the presence of Lewis acid catalyst Treatment of ketoaldehyde (PhCOCH(2)CH(2)CHO) with 1a under BF3 . OEt(2) catalysis gave 3-methylene-1-phenyl-8-oxabicyclo[3.2.1]octane in one pot.
