A facile synthesis of Enantiopure γ-Amino-And γ-Hydroxy-β-Ketosulfones
摘要:
Enantiopure gamma-amino and gamma-hydroxy-beta-ketosulfones have been synthesized in high yields from alpha-diazoketones derived from the alpha-amino and alpha-hydroxy acid chiral pools.

Starting from 'chiral-pool' derived gamma-amino-beta-ketosulfones, a facile synthesis of enantiopure alpha-amino ketones has been developed via an alpha-alkylation-desulfonation sequence. Extension of this methodology to enantiopure a-acetoxy ketone synthesis,however, have met with limited success. (C) 1998 Elsevier Science Ltd. All rights reserved.
