(2+1) CYCLOADDITION OF CHLORO(PHENYLTHIO)CARBENE TO VINYL SILANES. A FACILE SYNTHESIS OF HIGHLY FUNCTIONALIZED CYCLOPROPANES
Vinylsilanes 1d-h react with chloro(phenylthio)carbene 2 to give functionalized silylcyclopropanes 3 with high Z-stereoselectivity.For 3g, the relative configuration was proven by an X-ray structural analysis.Synthetic modifications of 3 include eliminati
