Abstract
Various N-acyl lactams were prepared in good yields from free carboxylic acids and lactim ethers by employing 1-methyl-2-chloropyridinium iodide as a coupling reagent. Similarly, 1-acyl-3-methyl-4-imidazoline-2-thione or 3-acyl-2-thiazolidinethione was prepared in a fairly good yield from carboxylic acid, and 1-methyl-2-methylthioimidazole or 2-methylthio-2-thiazoline, respectively.Keywords
