Process for optically active 3-(methane-sulfonyloxy)thiolane and analogs |
| abstract |
Intermediates and a stepwise process for the conversion of D-methionine or certain of its derivatives to optically active compounds of the formula ##STR1## wherein R is (C 1 -C 3 ) alkyl, phenyl or tolyl. The latter compounds are in turn useful as an intermediate in the preparation of penem antibiotic 5R,6S-6-(1R-hydroxyethyl)-2-(1R-oxo-3S-thiolanylthio)-2-penem-3-carboxylic acid and corresponding pharmaceutically acceptable salts and esters. |
