Pyrido- and [1, 4]-oxazinoisoquinolines, bis-tetrahydroisoquinolines, the alkaloid corydaldine, cleavage products, and a series of intermediates were prepared from homoveratrylamine and dibasic acids (glutaric and diglycolic) using a Bischler–Napieralski reaction. Their structures were confirmed using IR and NMR spectra and an x-ray crystal structure analysis.
