Two series of indolyldiketopiperazines were synthesized starting from methyl 1‐substituted‐1,2,3,4‐tetrahydro‐β‐carboline‐3‐carboxylate hydrochlorides via N‐bromo‐succinimide (NBS) as an important reagent. All eight compounds were characterized by nuclear magnetic resonance (NMR) and elemental analysis. Furthermore, the mechanisms of NBS‐reacted rearrangements are also discussed. Chirality 26:790–792
Methyl 1-imidazolecarbodithioate as a thiocarbonyl transfer reagent: a facile one-pot, three-component synthesis of novel 2-substituted-5-aryl-1-oxo-3-thioxo-1,2,3,5,11,11a-hexahydro-6H-imidazo-[1,5-b]-β-carbolines

An efficient one-pot, three-component synthesis of novel 2-substituted-5-aryl-1-oxo-3-thioxo-1,2,3,5,11,11a-hexahydro-6H-imidazo-[1,5-b]-beta-carbolines employing 1-aryl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylates, primary amines (or amino acid esters) and methyl 1-imidazolecarbodithioate as the thiocarbonyl transfer reagent is reported.
