摘要：

Alkylation under phase transfer conditions of the chiral glycine synthon 2 (prepared from the commercially available Oppolzer chiral sultam) with fluorinated analogues of 3,4-dimethoxybenzyl chloride proceeded with high diastereoselectivity. Hydrolysis of the Schiff base, removal of the chiral auxiliary and HBr demethylation produced 2-, 5-, 6-fluoro- and 2,6-difluoro-L-DOPA in e.e. of >99%. (C) 2002 Elsevier Science Ltd.
