Efficient one-pot double Buchwald–Hartwig coupling reaction on 5-phenyl-4-phenylsulfonyl-2,3-dihydrofuran derivatives
摘要:
We report a new and efficient method of conducting a one-pot double Buchwald-Hartwig coupling reaction on 2,3-dihydrofuran derivatives bearing two bromine atoms. This rapid and convenient synthesis allows us to access a great variety of original mixed dicoupled compounds. The strategy appears promising for combinatorial chemistry and pharmacomodulation studies. (C) 2011 Elsevier Ltd. All rights reserved.

An efficient and broadly applicable protocol for the aerobic coupling of styrenes with sulfonylhydrazides has been developed that affords β-ketosulfones bearing various functional groups in moderate to excellent yields. The preliminary experimental results support the involvement of active benzyl radical species, and a radical pathway was therefore proposed for the reaction.
