Proton magnetic resonance study of the conformation of the pyrrolidine ring in some proline-thiohydantoins

, 1988
The conformational behaviour of a series of N-substituted thiohydantoins of proline was studied by proton NMR. The pseudorotational parameters of the proline moiety were calculated from the ten vicinal proton-proton coupling constants assuming a two ...

It is “2-imino-4-thiazolidinones” and not thiohydantoins as the reaction product of 1,3-disubstituted thioureas and chloroacetylchloride

, 2008
The products obtained by the reaction of 1,3-disubstituted thioureas with chloroacetylchloride are actually 2-imino-4-thiazolidinone derivatives and not thiohydantoins as previously reported (M. Kidwai, R. Venkataraman and B. Dave, Green. Chem., 2001, 3,

Sequencing of peptoid peptidomimetics by Edman degradation

, 1998
The direct identification of resin-bound peptoid peptidomimetics by sequencing is described. The N-terminus of the peptoid was treated with phenyl isothiocyanate, after which the N-terminal peptoid residue was cleaved from the resin as its thiohydantoin ...
