摘要

While investigating the synthesis of hydroxy-and amino-substituted pyrrole [1, 2-b] isoquinolines (Scheme I, 4?, 1, Cdihydrobenzo [c]-1, 5-naphthyridin-2 (3H)-one (6a) was obtained as the exclusive product from an attempted Beckmann rearrangement of 3a. Although partially reduced benzo [c]-1, 5-naphthyidines (eg, 5, 6-dihydr0-~ and 5, 6, 6a, 7, 8, 9, 10, 10a-octahydrobenzo [c]-l, 5-naphth~ idine4) are known, the reported syntheses do ...
