Formation of enamides via palladium(II)-catalyzed vinyl transfer from vinyl ethers to nitrogen nucleophiles

Matrix presented. Palladium(II) complexes catalyze the formation of enamides via the formal cross-coupling reaction between nitrogen nucleophiles and vinyl ethers. These vinyl transfer reactions proceed in good yields with amide, carbamate, and sulfonamide nucleophiles, and the optimal catalyst is (DPP)Pd(OCOCF3)2 (DPP = 4,7-diphenyl-1,10-phenanthroline).

Phase-transfer catalyzed asymmetric arylacetate alkylation

Phenethyl arylacetates are alkylated under phase-transfer conditions with cinchona catalysts with alkyl halides in high yield with excellent enantioselectivity (84-99% ee) following recrystallization. Cinchonidine (CD) derived catalyst gave the (R)-product and cinchonine (CN) catalyst produced the (S)-product. The phenethyl (PE) ester group is removed, using ammonium formate and catalytic Pd/C, to give alkylated carboxylic acid products in high selectivity. The utility of the approach is demonstrated by a direct synthesis of (S)-naproxen.

Promotion of reaction of N-H bonds with triarylbismuth and cupric acetate

Arylation of a diverse group of N-H containing compounds at room temperature with triarylbismuth and cupric acetate in the presence of a tertiary amine promoter, such as triethylamine or pyridine, is described. This mild and highly efficient procedure, which is based on Barton’s earlier work on the arylation of amines, can be applied to amides, imides, ureas, carbamates, and sulfonamides.
