A 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. In the experiment, the researchers used many compounds, for example, 2-Ethynylthiophene (cas: 4298-52-6Application In Synthesis of 2-Ethynylthiophene).
2-Ethynylthiophene (cas: 4298-52-6) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Application In Synthesis of 2-Ethynylthiophene
