Manganese(III) acetate-mediated tandem radicalcyclization reactions of methylenecyclopropanes with methyl substituted dicarbonyl compounds in acetic acid give dihydronaphthalene derivatives in moderate yields under mild conditions.
anoate, a valuable chiral intermediate for the synthesis of lactacystin, was obtained in high yield and excellent anti-diastereoselectivity. The ketoreductase catalyzed reduction of α-cyanomethyl- and α-cyanoethyl-β-keto esters to form the corresponding opticallypure β-hydroxy esters, which are chiral intermediates for the synthesis of opticallypure α-substituted γ-butyro and δ-valerolactams, was

α-cyanomethyl-β-dicarbonyl compounds with amines catalyzed by p-TsOH affords the corresponding enamines in good yields. Base catalyzed cyclization via the addition of an amine moiety to the carbon–nitrogentriplebond of nitrile furnished 2-aminopyrroles in high yields.
