Chemoselective Chemical and Electrochemical Deprotections of Aromatic Esters
摘要:
Alcohols can be easily and chemoselectively deprotected from the corresponding aromatic esters by using either Sml(2)/HMPA or by electrolysis in the presence of a proton source.
The mechanism of the monoelectronic reduction of aromatic esters has been investigated. The unexpected synthetic utility of the toluate moiety in the deoxygenation of alcohols and the allylation of ketones is also reported. Finally, the use of aromatic esters as robust, though easily removable, protecting groups is depicted. (C) 2009 Elsevier Ltd. All rights reserved.

The electrolysis of toluateesters leads smoothly to the formation of the radical of the alkyl fragment. This property has been used to develop a new electrochemical deoxygenation reaction.
