Synthesis of pyrido[2,3-e]pyrrolo[1,2-a]pyrazine derivatives via tandem iminium cyclization and smiles rearrangement
(Chemical Equation Presented) The tandem iminium cyclization and Smiles rearrangement of pyridinyloxyacetaldehyde 1 and a primary amine generated a novel pyrido[2,3-e]pyrrolo[1,2-a]pyrazine scaffold. TFA was discovered to be an efficient catalyst in the r

REINVESTIGATION OF A CYCLIZATION REACTION OF 2-HYDRAZINO-3-(1H-PYRROL-1-YL)PYRIDINE
The reaction of 2-hydrazino-3-(1H-pyrrol-1-yl)pyridine (3) with acetylacetone affords 2-(3,5-dimethyl-1H-pyrazol-1-yl)-3-(1H-pyrrol-1-yl)pyridine (7) rather than 3,5-dimethyl-10-(1H-pyrrol-1-yl)pyridotriazepine (5), as previously reported.
