Synthesis of isoquinolines by intramolecular aza-Wittig reaction
Abstract
Isoquinolines (3) and (5) are formed under miled neutral conditions by intramolecular aza-Wittig reactions of iminophospranes, readily derived from azides (1) and (4) with trithyl phosphite, the azafluranthene (7) can also be prepared from the isolable iminophosphoranes (8), (9), and (10).
