Nucleophile-Induced Ring Enlargement of 1-(1-Iodoalkyl)silacyclobutane and 1-(1,2-Epoxyalkyl)silacyclobutane into Silacyclopentane. Application to the Syntheses of 1,4-Diol, 4-Alken-1-ol, and 1,4,5-Triol
Nucleophile-Induced Ring Enlargement of 1-(1-Iodoalkyl)silacyclobutane and 1-(1,2-Epoxyalkyl)silacyclobutane into Silacyclopentane. Application to the Syntheses of 1,4-Diol, 4-Alken-1-ol, and 1,4,5-Triol
Treatment of 1-(1-iodoalkyl)-1-silacyclobutanes with t-BuOK or AgOAc provided 2-alkyl-1-silacyclopentanes which were easily converted into 1,4-diols by oxidative cleavage of carbonsilicon bonds.
