A number of aromatic aza-analogues of juvabione and dehydrojuvabione have been synthetized by treatment of substituted benzylamine with 3-methylbutanoyl chloride and 3-methyl-2-butenoyl chloride.Reaction of substituted phenoxyacetyl chlorides with isoprop
A CONVENIENT METHOD FOR THE SYNTHESIS OF CARBOXAMIDES AND PEPTIDES BY THE USE OF TETRABUTYLAMMONIUM SALTS

Various carboxamides and peptides are prepared in good yields by treatment of free acids and amines in H2O-dichloromethane or aqueous THF with bis(o-nitrophenyl) phenylphosphonate in the presence of tetrabutylammonium hydrogen sulfate or bromide.Carboxylic esters are also successfully converted to amides via carboxylate salts in one-pot.
