Photocyclization of succinimides with an N-acyl group in the side chain gave bi- and tricyclic pyrrolopyrazines, some of which were converted to tricyclic amines by reduction.The stereochemistry of pyrrolopyrazine derivatives is discussed on the basis of the results of X-ray analysis and carbon-13 nuclear magnetic resonance spectroscopy.Keywords - succinimide; photocyclization; pyrrolo-pyrazine; hydrogen abstraction; X-ray analysis; 13C-NMR spectrum; tricyclic diamine
