Efficient synthesis of tertiary α-hydroxy ketones through CO 2-promoted regioselective hydration of propargylic alcohols

He, Haitao,Qi, Chaorong,Hu, Xiaohan,Guan, Yuqi,Jiang, Huanfeng

supporting information, p. 3729 - 3733 (2014/08/05)

A carbon dioxide-promoted and silver acetate-catalyzed hydration of propargylic alcohols for the efficient synthesis of tertiary α-hydroxy ketones has been developed. The reaction is proposed to proceed via a tandem process of carbon dioxide incorporation into propargylic alcohols and subsequent hydrolysis. This journal is the Partner Organisations 2014.
