Straightforward synthesis of 1,2,3-tricarbonyl systems
摘要:
A simple two-step protocol for the preparation of alpha,beta-diketo amides is described. The first step involves condensation of the anion of an alpha-phenylthio amide with an aldehyde. This is followed by oxidation of the resulting beta-hydroxy alpha-sulfide with the Dess-Martin periodinane. The vicinal tricarbonyl system is obtained in good to excellent yields.
