摘要

The protection of carbonyl compounds as acetals, dithioacetals and oxathioacetals is an important aspect of the total synthesis of complex natural products. 1., and Among these, oxathioacetals and dithioacetals are important because they are considered more stable than the corresponding O,O-acetals under acidic conditions and are also useful in organic synthesis as acyl carbanion equivalents in CC bond forming reactions. 2., , and Moreover, S,S-acetals can be used ...
