Carbon-13 and Proton NMR Shift Assignments and Physical Constants of Some L-Menthol Derivatives

Abstract

Several acyl derivatives of L-menthol, which find potential use in the perfumery and flavor industry were directly prepared in a single step reaction from L-menthol in the presence of a suitable catalyst. The ¹H - and ¹³C-NMR spectroscopic data of these derivatives along with their physical constants are reported.
