摘要
Coupling of the N-acyl tert-leucine derivative 2 with a variety of amines 3a-g gave amides 4a-g in good to excellent yields (75-95%) with minimal epimerisation (less than or equal to 3%) at the tert-leucine stereogenic centre. Limitations of the method are discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
