combination of an Ugi-4CR and a transition metal-free selective N−S bond cleavage and C−N bond activation, diverse primary amides and α-ketoamides were simultaneously obtained in a highly efficient, rapid, and step-economical manner. The reaction features broad substrate scope, excellent functional-group tolerance, and exclusive selectivity. Primary amides derived from the pharmaceuticals probenecid and febuxostat
