A new entry for the deprotection of monothioacetals and dithioacetals: Silver nitrite - iodine system
摘要:
A new reagent system (silver nitrite-iodine) was developed for demothioacetalization and dedithioacetalization reactions. The reaction using this reagent afforded the parent carbonyl compound in excellent yield under mild conditions.
