Abstract

A novel and mild protocol for the hydration of electron-deficient allenic esters and ketones into various 1,3-dicarbonyl compounds is described. The hydration of allenes promoted by oxone in DMF afforded the corresponding products in moderate to good yields. This work features the employment of only a catalytic amount of inexpensive and nontoxic solid reagent oxone (2KHSO 5 ·KHSO 4 ·K 2 SO 4 ), avoiding the utility of toxic metals or traditional Brønsted acids, in a green version of viewpoint. A possible reaction mechanism for this transformation is also primarily proposed. [ABSTRACT FROM AUTHOR]
