Low molecular weight chromogenic thrombin peptide substrates, p-nitroanilides of short peptides protected at their N-terminal amino group, were prepared by solid-phase peptide synthesis on polystyrene-divinylbenzene polymer with trityl groups with preliminary attached p-phenylene diamine moiety. After the cleavage from the resin peptide p-aminoanilides were mildly oxidized to p-nitroanilides with the mixture of potassium sulfate and persulfate. Adsorption onto polymer support Bio-Beads SM-2 with further elution by acetonitrile allowed easy separating peptide p-nitroanilides from the oxidizer and obtaining the thrombin chromogenic substrate preparations with the target substance contents of not less than 95% and yields of 30-40%. Thrombin effectively catalyzed hydrolysis of the prepared substrates with KM and Vmax values of 29-134 mM and 0.03-1/16 mM/s, respectively.

Stannane-mediated radical addition to methylideneimidazolidinones occurs with good to excellent diastereo-selectivity. The stereochemical outcome of addition is highly dependent on the nature of the N1 substituent on the imidazolidinone ring.
