Asymmetric synthesis of β-hydroxy sulfones by reduction of chiral β-keto sulfones
摘要:
Chiral beta-keto sulfones 3 have been prepared from enantiomerically pure sulfinic acids 2 derived from (R)- and S-methylbenzylamine. Enantiospecific reduction of these ketosulfones 3 can be achieved using different hydrides affording beta-hydroxy sulfones. Opposite configurations on the newly created stereocenter is obtained with DIBAL-H or LAH as reducing agents. Copyright (C) 1996 Elsevier Science Ltd
