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.
