摘要：
An alternative and cost effective route for the resolution in high ees (95-99%) of (+/-)-mandelic- and (+/-)-2-(chlorophenoxy)propionic- acid derivatives is reported. The key step involves the covalent derivatization and separation of their diastereomeric amides with (R)- or (S)-alpha-arylethylamines. (C) 1999 Elsevier Science Ltd. All rights reserved.
