Abstract
Abstract ( E )-Alkenylsilanes were synthesized with high stereoselectivity by the diastereoselective addition of the dimethylphenylsilyllithium to the trans -2-phenylthiocyclobutyl ketones and the Lewis acid-promoted stereospecific ring opening reactions of the resulting cyclobutanemethanol derivatives. ( E )-1,5-Disubstituted-1,5-dienylsilanes and germanes were also produced stereoselectively by the similar zinc salt-catalyzed ring opening reaction of α-dimethylphenylsilyl- or α-triethylgermyl-1-⦜2-(trimethylsilyl-methyl)cyclobutane]methanol derivatives.
