Benzhydryldimethylsilyl Allylic Silanes: Syntheses and Applications to [3 + 2] Annulation Reactions
摘要:
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.

[GRAPHICS]A stereoselective synthesis of gamma -butyrolactones by the [3 + 2] annulation of allylic silanes with N-chlorosulfonyl isocyanate (CSI) was developed. An enantioselective total synthesis of (+)-blastmycinone was accomplished using this annulation as the key step.
