We have realized that N-formylations of free amines of some drug leads can improve PK/PD property of parent molecules without decreasing their biological activities. In order to selectively formylate primary amines of polyfunctional molecules, we have sought a mild and convenient formylation reaction. In our screening of N-formylation of an alpha-amino acid, l-phenylalanine, none of formylation conditions reported to date yielded the desired HCO-l-Phe-OH with satisfactory yield. N-formylations of amino acids with HCO2H require a water-containing media and suppress polymerization reactions due to the competitive reactions among carboxylic acids. We found that N-formylations of alpha-amino acids could be achieved with a water-soluble peptide coupling additive, an Oxyma derivative, (2,2-dimethyl-1,3-dioxolan-4-yl)methyl-2-cyano-2- (hydroxyimino)acetate (2), EDCI, and NaHCO3 in water or a mixture of water and DMF system, yielding N-formylated alpha-amino acids with excellent yields. Moreover, these conditions could selectively formylate primary amines over secondary amines at a controlled temperature. A usefulness of these conditions was demonstrated by selective formylation of daptomycin antibiotic which contains three different amino groups.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. category: catalyst-ligand
