A general and excellent acylation reagent, diacyl disulfide, was uncovered for efficient ester formation enabled by DMAP (4-(N,N-dimethylamino)pyridine) catalysis. This protocol offered a promising synthetic platform on site-selective acylation of phenolic and primary aliphatic hydroxyl groups, which greatly expanded the realm of protecting group chemistry. The importance of the reagent was also reflected
为了通过DMAP(4-(N,N-二甲基氨基)吡啶)催化实现有效的酯形成,发现了通用且优异的酰化试剂二酰基二硫化物。该方案为酚和伯脂族羟基的位点选择性酰化提供了一个有希望的合成平台,这大大扩展了保护基化学的领域。该试剂的重要性还体现在其出色的耐湿性,高效率以及在合成化学和生物学上有意义的天然产物修饰方面的潜力。
