โœฆ Synopsis


The selective monoamidation of diesters and amidation of esters mediated by Lewis acids are described. The selective amidations of dimethyl pyridine-2,5-dicarboxylate (1) and dimethyl 2,3-indole-dicarboxylate (4) with primary and secondary amines mediated by MgCl 2 or MgBr 2 under mild conditions gave the corresponding ester-amides in high yield.

N-tosyl amides and lactams can be prepared easily and under mild conditions by the inter-or intramolecular condensation of carboxylic acids and secondary sulfonamides. The coupling reagent used is dicyclohaxylcarbodiimide (DCC) in the presence of 4-pyrrolidioopyridine (4-PPY) and the reactions proce
