Synthesis of chiral NADH model compounds in the pyrrolo[3,2-b]pyridine series : models with a chiral group on the pyrrole nitrogen or on the carboxamide side chain
The synthesis of chiral NADHmodel compounds in the pyrrolo[3,2-b]pyridine series is described, using various strategies. The first route involved alkylation of the pyrrole nitrogen of a nitropyrrole carboxylate followed by a ring closure reaction in a [3+3] process. The same [3+3] process was used in the second route in order to synthesize the pyrrolo[3,2-b]pyridine structure. Various alkylation methods
