A selective, practical, and scalable aerobic oxidation of alcohols is described that uses catalytic amounts of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and HNO3, with molecular oxygen serving as the terminal oxidant. The method was successfully applied to the oxidation of a wide range of benzylic, propargylic, and allylic alcohols, including two natural products, namely, carveol and podophyllotoxin
描述了一种选择性,实用且可扩展的酒精好氧氧化方法,该方法使用催化量的2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)和HNO 3,分子氧作为末端氧化剂。该方法已成功应用于多种苄醇,炔丙基醇和烯丙基醇的氧化,包括两种天然产物,即香芹酚和鬼臼毒素。该条件也适用于对甲氧基苄基醚的选择性氧化脱保护。
