A general one-pot procedure is described that rapidly converts acrylic acid to anilides upon sequential treatment of the acid in dimethylacetamide (DMAC) with thionyl chloride and stoichiometric amounts of anilines in 88-98% yields, with DMAC offering rate and stability advantages over the use of DMF. The use of DMAC was extended to other organic acids in forming anilides. Benzylamine amides can also be formed using stoichiometric amounts of benzylamine and brought to completion by warming in the absence of additional base. In addition, it was shown that tert-butylamides can be easily formed with the addition of excess tert-butylamine at 20 °C.

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.
