Taurine and structurally diverse substituted taurines have been synthesized by peroxyformic acid oxidation of the thiazolidine-2-thione intermediates generated from vicinal amino alcohols or aziridines and carbon disulfide. Thestereochemistry and mechanisms of the reactions are disscussed. The method is a salt-free and versatile route, convenient in terms of purification, and can be used to synthesize
Both sulfonopeptides and phosphonopeptides are important analogs of naturallyoccurring peptides and have been widely used as enzyme inhibitors and haptens for producing catalytic antibodies due to their tetrahedrally structural features. A series of hybrid sulfonophosphinodipeptides composing of taurines and 1-aminoalkylphosphinic acids were first and conveniently synthesized in satisfactory to good
strong: A new, robust method allows the measurement of residualchemicalshiftanisotropies for the determination of conformation and configuration of molecules in organic solvents. The power of the method is shown by the example of estrone and 13‐epi‐estrone (see structures), where only the combined use of residualchemicalshiftanisotropies and residual dipolar couplings leads to the distinction of the
