Synthesis of 3-Ethyl-4-methyl-1,5-dihydro-2H-pyrrol-2-one by Novel Palladium(II)-Catalyzed Cyclization and Ring-Closing Metathesis

Synthesis of 3-ethyl-4-methyl-1,5-dihydro-2H-pyrrol-2-one is described starting from commercially available allylamine and 4-methoxybenzylamine employing palladium-catalyzed cyclization or ring-closing metathesis as the key steps.

Reduction of five-membered α,β-unsaturated lactones and related compounds with the Ni2+/BH4- system

The reductions of an α,β-unsaturated lactone (5) and lactam (7) with the Ni2+/BH4- system resulted in the formation of cis-hydrogenated products (8a and 9a) with high stereoselectivity. The cis products (8a and 9a) were ea
