Novel optically active pyrazole ligands derived from (+)-3-carene
摘要:
Reactions of chiral beta -diketone with racemic hydrazines as well as reaction of chiral pyrazole with cyclohexene epoxide and trans-stilbene epoxide have been examined as the routes to optically active pyrazolylethanols. Diastereomerically pure products have been isolated by crystallization or column chromatography in good yields. (C) 2001 Elsevier Science Ltd. All rights reserved.

A new series (except compound 3a) of d-ring modified acid hydrazides of podophyllotoxin were synthesized by cleaving of its d-ring with various hydrazines. Furthermore, the synthesized compounds were screened for their anticancer activity against human tumor cell lines i.e., MCF-7, HeLa and A-549 and among the synthesized compounds 3c and 3f have shown significant anticancer activity almost similar
