摘要：

A series of novel optically active oc-amino acids, containing a pyrazole ring, which can be regarded as building blocks for peptidomimetics, have been prepared starting from readily available oc-amino acids. The synthetic strategy employed allows the regio- and stereoselective preparation of 1,3- or 1,5-substituted pyrazolyl rings. The pyrazole containing peptidomimetics can be considered as analogues of peptides with a cis amide bond. (C) 1999 Elsevier Science Ltd, All rights reserved.
