Je. Moussounga et al., A NOVEL SYNTHESIS OF QUINOLINE-4(1H)-THIO NES BY THERMOLYSIS OF ENAMINOTHIOESTERS, Bulletin de la Societe chimique de France, 132(2), 1995, pp. 249-257
A novel synthesis of quinoline-4(1H)-thiones by thermolysis of enamino
thioesters. A novel synthesis producing good yields of quinoline-4(1H)
-thiones and involving the flow vacuum pyrolysis of enaminothioesters
has been developed. The results are discussed in terms of the intermed
iate formation of iminothioketenes; whose electrocyclization leads to
the title compounds.
