Abstract

The reaction of dimethyl 1,4-tetrahydrothiazone-3,5-dicarboxylate with phenyl isocyanate and phenyl isothiocyanate leads to 2,4-dioxo-3-phenyl-9-methoxycarbonyl-7-thia-1,3-diazabicyclo[3.4.O]nonane and its thioxo analog. It is shown that only the trans isomer of the starting diester undergoes the reaction.
