✦ Synopsis

The line separations from geminal and vicinal CH-couplings in simple glycidic esters are found to be within narrow ranges. They can be used for the assignment of carbon resonances and epoxide configurations.

Glycidic esters are conventionally synthesized by the Darzens condensation, which however, leads to mixtures of diastereomers. In the direct epoxidation of double bonds with m-chloroperbenzoic acid (MCPBA), on the other hand, the configuration of the olefin is retained in the epoxide formed. Thus we prepared

## Abstract The ^13^C NMR spectra of two __N__‐methylimidazole‐substituted sterol esters are discussed. The calculated shifts are compared to those obtained experimentally. For one of the sterol esters the experimental and calculated data show good agreement, and the substituent increments can be e
