Abstract
New chiral pyrazoles, (4R,7R)-4-methyl-7-isopropyl-3-phenyl- (3-phenyliso menthopyrazole cis-1), (4R,7S)-4-methyl-7-isopropyl- (1-menthopyrazole; trans-2), (4R,7R)-4-isopropyl-7-methyl- (iso carvomen-thopyrazole, cis-3) and (4R,7S)-4-isopropyl-7-methyl-4,5,6,7-tetrahydro-1H-indazole (carvomenthopyra-zole, trans-3) were prepared. The diastereomeric pairs of these 1–3 were structurally characterized by NMR spectroscopy. The subtle differences of structures of 1–3 should induce the useful effects for a chiral auxiliary or a chiral catalyst.
