Contribution à la connaissance des o‐menthols et des o‐menthones (carquéjanols et carquéjanones). 3^e communication

Abstract

The alcohols (+)‐carquejanol, (−)‐neocarquejanol, (−)‐isocarquejanol, and (−)‐neoisocarquejanol are described, and their conformations and configurations are studied by IR., NMR. and mass spectroscopies. Isocarquejanol is a mixture of conformers approximatively 50:50 with, respectively, axial and equatorial OH.

“…The configurations of o-menthols were deduced, using IR, NMR, and mass spectral data, by Ferretti-Alloise ei al. (203). Stereochemical studies were performed by ¡ruga and Watanabe (681) on 4-methyl-10-nor-8-oxomenthol:> by circular dichroism.…”
