Paragraph 0025, (2017/09/01)
The invention provides a method for efficiently synthesizing an alpha-acyloxy ketone compound containing different substitute functional groups. According to the method, acetylacetone copper is taken as a reaction catalyst, t-butylhydroperoxide is taken as an antioxidant, ketone compounds and terminal alkyne compounds are taken as reaction substrates, and an organic solvent is added into a reaction system. The method has the advantages that the catalyst is cheap and easily available; reaction conditions are mild, safe and reliable; and the productivity of an obtained target product is relatively high. According to the method, the problem that a traditional alpha-acyloxylation reaction system is single is solved, and a novel acyloxylation reagent is provided; and the method has good industrial application prospects.

A simple and efficient one-pot NBS/DBU-mediated method has been developed for the synthesis of α-acyloxyketones from various benzylic secondary alcohols and carboxylic acids. Through this methodology, a series of α-acyloxyketones could be obtained in good to excellent yields under mild conditions. Importantly, this new reaction avoids the direct usage of toxic metal catalysts or potentially dangerous peroxide oxidants.
