A novel method for the deblocking of the dithioacetals and oxathioacetals is described. Periodicacidundernonaqueousconditions has been used for the deprotection of the dithio- and oxathio-derivatives to the corresponding carbonyl compounds. This simple high-yield transformation is conveniently carried out in nonaqueous medium and works well with complex sensitive aldehydes and in the presence of
