A highly practical and general palladium-catalyzed methodology for the α,β-dehydrogenation of esters and nitriles is reported. Generation of a zinc enolate or (cyanoalkyl)zinc species followed by the addition of an allyl oxidant and a palladium catalyst results in synthetically useful yields of α,β-unsaturated esters, lactones, and nitriles. Preliminary mechanistic investigations are consistent with reversible β-hydride elimination and turnover-limiting, propene-forming reductive elimination.
Conformationally constrained renin inhibitory peptides: γ-lactam-bridged dipeptide isostere as conformational restriction

A model of the conformation of the enzyme-bound inhibitor of human renin suggested the possibility of a γ-lactam conformational restriction at the P2-P3 site. Synthetic routes to these γ-lactam dipeptide isosteres and their incorpora
