Abstract
Abstractcis‐ and trans‐5‐Ethoxy‐1,3‐oxathiolane‐2‐carboxylic acids were obtained in pure form. The cis isomer was resolved into its enantiomers through diastereoisomeric salt formation with enantiomerically pure α‐methylbenzylamine. Reduction of the salt followed by benzoylation led to 2‐benzoyloxymethyl‐5‐ethoxy‐2(R)‐5(S)‐1,3‐oxathiolane and 2‐benzoyloxymethyl‐5‐ethoxy‐2(S)‐5(R)‐1,3‐oxathiolane, useful intermediates in nucleoside chemistry. © 1993 Wiley‐Liss, Inc.
