Epoxidation of 597 with H2O2 in the presence of dinuclear peroxotungstate catalyst K2[W2O3(O2)4(H2O)2]314 gave 598 in 99% yield and 92% de. Ammonolysis of bromide 598 in aqueous ammonia was spontaneously followed by an intramolecular ring opening of the epoxide (60% overall yield based ...
In the title compound, C10H18N2O4S2·2H2O, the two cysteine moieties (zwitterions), separated by the rigid butene-1,4-diyl chain, adopt different conformations. These are characterized by the fact that the first S atom is anti to the carboxyl group in one moiety while the second S atom ...
