Mild cleavage of aryl mesylates: methanesulfonate as potent protecting group for phenols.

Tobias Ritter1, Kyrill Stanek, Igor Larrosa, Erick M Carreira.   

Abstract

[reaction: see text] A mild protocol for the chemoselective deprotection of aryl methanesulfonates is described. The transformation can be conducted on highly functionalized substrates and renders the methanesulfonate a useful, previously underutilized protecting group for phenols.
