Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. In a patent, 76186-04-4, name is (S)-4-Isopropylthiazolidine-2-thione, introducing its new discovery. Computed Properties of C6H11NS2
CycloSal-nucleosyl-phosphate triesters are a known class of highly effective nucleotide prodrugs (pronucleotides) of antivirally active nucleoside analogues. Until recently, the synthesis of these compounds always gave diastereoisomeric mixtures. Then, a convergent route for the stereospecific synthesis of cycloSal-triesters was described to give isomerically pure cycloSal-prodrugs for the treatment of viral diseases. Here, the development of a stereoselective synthesis of these pronucleotides using various chiral auxiliaries is described. In contrast to pyrrolidine- or pyrrolidinone derivatives it was found that a thiazolidine derived from valinol fulfilled all three requirements to act as a suitable chiral moiety, allowing: (i) strong chirality transfer, (ii) the formation of separable diastereoisomeric intermediates, and (iii) a suitable leaving group that allows the introduction of the nucleoside analogue (e.g., d4T) in the final step under mild reaction conditions. The title compounds were obtained with very high diastereoisomeric excesses of more than 95%. The development of a stereoselective route to cycloSal-nucleotides of thymidine and d4T based on the use of various chiral auxiliaries is reported. The target chiralphosphates were obtained with very high diastereoisomeric excesses of more than 95%.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Computed Properties of C6H11NS2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 76186-04-4, in my other articles.
