overall yields (52–80%). A convenient, rapid and widely applicable one-pot procedure has been developed for the synthesis of acetylenedicarboxamides from various primary and secondary amines, including amino acidderivatives, protectedcarbohydrates, and fluorescent labels. By using DMTMM for amide coupling, acetylenedicarboxylic acid was directly converted into acetylenedicarboxamides in highly competitive
