Popis:	The Bischler-Napieralski cyclization of the 1,2-diaryiethylamides in a “one-pot” process using ethyl poly-phosphate as the reagent only yields the dihydroisoquinolines in certain cases. The trans-stilbenes and in-danes are obtained as neutral products and sometimes as sole products. Results clearly indicate the effect of aryl group substitution on the course of the reaction and the relationship between the Bischler-Napieralski and Ritter reactions.
