Abstract
Treatment of tetraoxa-cages 1a-f with Lewis acids such as TlC4, AlCl3, BF3 . OEt(2) and MeSO(3)H in dichloromethane at 25 degrees C gives th e rearrangement products 2a-f in 90% yields regioselectively and stere oselectively; a novel hydride rearrangement of the acetal group of tet raacetal tetraoxa-cages mediated by Lewis acids.
