(Chemical Equation Presented) An expedient, five step synthesis of caprolactam 1 is reported starting from natural L-homoserine. The key step is a chemoselective reductive cyclization of α,β-unsaturated nitrile 10 mediated by Raney-Co type metals. This hydrogenation is extensively investigated in order to account for the observed product distribution and yields.

-
, (2008/06/13)
Aldehyde derivatives with a specific calpain inhibiting activity and a platelet-aggregation inhibiting effect with formula (I) or formula (II): wherein R1 represents an aromatic hydrocarbon group, a heterocyclic group, or a group of-X-R3 in which X represents O,-S(O)m-(m = 0, 1, or 2), and R3 represents an aromatic hydrocarbon group, a heterocyclic group, or an alkyl group; Z represents R?-Y-or R?O-CH(R?)-in which Y represents a 3-to 7-membered nitrogen-containing saturated heterocyclic group, or a single cyclic saturated hydrocarbon group, R? represents an alkyl group, an alkenyl group, an alkynyl group, an acyl group, a sulfonyl group, an alkoxycarbonyl group, a carbamoyl group, or a thiocarbamoyl group, R? represents hydrogen, an alkyl group, or an aromatic hydrocarbon group, and R? represents an acyl group, a carbamoyl group, a thiocarbamoyl group, or an alkyl group; and n is an integer of 1 to 5. wherein R?, R?, R?, and R1? are defined in the specification.
