posted on 2022-01-11, 22:14 authored by Jiakai Wu, Rongting He, Siliu Cheng, Limin Han, Hailong Hong, Ning ZhuA series of thiazolidine-2-one derivatives
were synthesized by
a three-component reaction of carbon dioxide, hydrogen sulfide, and
propargyl amines under mild conditions. The simultaneous incorporation
of carbon dioxide and hydrogen sulfide into the same organic product
was realized. Moreover, a reaction mechanism was proposed based on
the detailed NMR and FTIR study, which indicated that propargyl amine
reacted with CO2 first to form carbamate, followed by O/S
exchange with H2S to form thiocarbamate and the final cyclization
of thiocarbamate to form thiazolidine-2-one.
