We introduce a new class of arylsulfonylated cyclic acetals derived from carbohydrate structures which are synthesized with high yields under basic conditions. Deprotection methods for such acetals are also investigated. (C) 2000 Elsevier Science Ltd. All rights reserved.

A range of sugar-derived phenylsulfonylethylidene acetals were easily obtained from the corresponding diols and 1,2-bis(phenylsulfonyl)ethylene under basic conditions. Deprotection methods for such acetals have also been investigated.
