Cyclopentenone compounds are widely present in natural products and biologically active molecules, and act as very powerful synthons for the synthesis of a variety of bioactive target molecules. Therefore, it is of great research significance and application value to develop their synthetic methods. This article reports a novel method for the efficient synthesis of cyclopentenones by organic base-promoted [2+3] annulation reaction of arylglyoxal monohydrates with allyl phosphonium salts. This method displays metal-free, good chemoselectivity, mild reaction conditions, broad substrate scope, and short reaction time. The practical application of this method is demonstrated by the gram-scale synthesis and further transformation reactions.

Key words: organic base, [2+3] annulation, arylglyoxal monohydrates, allyl phosphonium salts, cyclopentenones
