摘要

Selective protection and deprotection of carbonyl groups are extremely important steps in modern organic chemistry. 1 1,1-Diacetates (acylals) are one of the essential carbonyl protecting groups due to their stability under both neutral and basic media as well as under acidic conditions. 2 The diacetates of α,β-unsaturated aldehydes are important starting materials for Diels–Alder reactions and also are useful intermediates in industries. 3 and 4 Moreover, the acylal ...
