Benzhydryldimethylsilyl allylic silanes: syntheses and applications to
A new silyl group, the benzhydryldimethylsilyl group, has been developed that is easily synthesized and that undergoes facile oxidation. The [3 + 2] annulation reactions of allylic silanes with this silyl group provide a variety of highly substituted five-membered carbocycles and heterocycles with high stereoselectivities. The silyl groups of these cyclic compounds have been oxidized to hydroxyl groups to demonstrate the general synthetic utility of the method.
