Reaction of ( S )-homoserine lactone with Grignard reagents: synthesis of amino-keto-alcohols and β-amino acid derivatives
摘要:
The ring-opening reaction of homoserine lactone with phenylmagnesium bromides was systematically examined. A reliable method to achieve beta-amino acid precursors was developed by tuning the reaction conditions to favor mono-addition to the carbonyl moiety of the lactone. (C) 2017 Elsevier Ltd.
