Abstract
The synthesis of 5, 6-dihydro 6-oxo pyrido [2, 3-e] pyrrolo [1, 2-a] pyrazine, and 5, 6-dihydro 6-oxo pyrazino [2, 3-e] pyrrolo [1, 2-a] pyrazine is described. The starting materials, 3-amino pyridine and 3-amino pyrazine are converted into pyrrolyl derivatives using 2, 5-dimethoxytetrahydrofuran in glacial acetic acid. Subsequent cyclizations of these latter afforded the title compounds. Proton nuclear magnetic resonance spectra are studied.
