Abstract
Alkyl sterols epimeric at C-24 isolated from the Atlantic scallop,Placopecten magellanicus, were analyzed by high resolution (220 MHz) nuclear magnetic resonance spectrometry, and their spectra compared with authentic samples. This technique was used to assign absolute stereochemistry in epimeric mixtures of 24 R and S 24-methylcholest-5-en-3β-ol, (22E)-24-methylcholesta-5,22-dien-3β-ol and 24-ethylcholest-5-en-3β-ol. It also allowed a semiquantitative estimate of the R/S isomers present in the mixture.
