Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines,Related Products of 76186-04-4, improving understanding of environmental issues, and development of new chemical products and materials. In a document type is Article, and a compound is mentioned, 76186-04-4, (S)-4-Isopropylthiazolidine-2-thione, introducing its new discovery.
The first diastereoselective synthesis of aryloxy phosphoramidate prodrugs of 3′-deoxy-2′,3′-didehydrothymidine monophosphate (d4TMP) is reported. In our approach, (S)-4-isopropylthiazolidine-2-thione 1 was used as a chiral auxiliary to introduce the stereochemistry at the phosphorus atom. In the last step of the developed reaction sequence, the nucleoside analogue d4T was introduced to a stereochemically pure phosphordiamidate which led to the formation of the almost diastereomerically pure phosphoramidate prodrugs 8a-d (?95% de). As expected, the individually prepared diastereomers of the phosphoramidate prodrugs showed significant differences in the antiviral activity. Moreover, the difference was strongly dependent on the aryl substituent attached to the phosphoramidate moiety.
