摘要：

The asymmetric synthesis of all stereoisomers of alpha-methylthreonine using a stereodivergent synthetic route starting from (S)- and (R)-N-Boc-N,O-isopropylidene-alpha-methylserinals is reported. The key step involves the asymmetric addition of methylmagnesium bromide to these aldehydes with a high level of asymmetric induction being observed. This methodology represents a powerful tool for the synthesis of different beta-substituted alpha-methylserines. (C) 2003 Elsevier Ltd. All rights reserved.
