Decarboxylation of fluorosulfones for the preparation fluoroalkylidene precursors
摘要:
The synthesis of fluorosulfones by alkylation of fluoroacetate derivatives is reported. Their decarboxylation reaction under Krapcho conditions is a convenient process to prepare fluorosulfones as reagents for fluoroalkene synthesis. (C) 2011 Elsevier B.V. All rights reserved.
Convenientaccess to homochiral fluoroalkenes is described via a Julia–Kocienski olefination reaction. The required homochiral fluorosulfone is synthesized by a Mitsunobu reaction from readily available enantiopure secondary alcohols.
