4-(Indol-3-yl)-2-pyrrolidone and its derivatives have been synthesized via sequential hydrogenation of indole-containing esters of 4-nitrobutanoic acid, alkaline hydrolysis of the resulting 3-methoxycarbonyl-2- pyrrolidones, and decarboxylation of the isolated 2-pyrrolidone-3-carboxylic acids. Structures of the products have been confirmed by IR, H-1 NMR, H-1-C-13 HMQC, and H-1-H-1 NOESY spectroscopy methods.
