A rapid, one-pot synthesis and mild procedure for the N-phthaloylation of α-amino carboxamides is described. In acetonitrile, these derivatives react with mono-methylphthalate in the presence of BOP and i-Pr2NEt to afford the intermediate Nα-[(o-methoxycarbonyl)benzoyl]amino carboxamides, which undergo rapid cyclization in the presence of aqueous sodium carbonate to afford the corresponding Nα-phthaloylamino carboxamides in excellent yields. The reaction also works efficiently with α-amino esters, α-amino alcohols and dipeptide esters or amides.
