The tripeptide Z-GlyPheLeuNH2 was continuously synthesized in a high yield from three amino acid derivatives, Z-Gly, PheOMe, and LeuNH2, by immobilized thermolysin (IMT) and immobilized alpha-chymotrypsin (IMC) in an organic solvent, ethyl acetate. The op

Phosphorus pentoxide and DMAP are used for amide bond formation from carboxylic acids and amines. Dipeptides and amides have been synthesized using this reagent in 42–77% yields and >99% ees. The protocol is attractive as it occurs at ambient temperature, the formation of organic by-products is minimal and the reagent can be readily quenched using water. Furthermore, excellent enantioselectivities are observed without the use of harsh triazole based additives.
Pd-catalyzed intramolecular C(sp2)-H amination of phenylalanine moieties in dipeptides: Synthesis of indoline-2-carboxylate-containing dipeptides

A palladium-catalyzed intramolecular C(sp2)-H amination of phenylalanine moieties in dipeptides is described. By this protocol, a series of indoline-2-carboxylate-containing dipeptides were synthesized from dipeptides. The N-protected amino aci
