A convenient oxidative demasking of 1,3-dithiolanes and dithianes to carbonyl compounds with TBHP

Abstract Regeneration of carbonyl compounds from their 1,3-dithiolanes and dithianes was achieved using tert -butyl hydroperoxide (TBHP, aq. 70%) in high yields. Thus, an efficient, economical and experimentally simple protocol for dethioacetalization has been demonstrated.
