Abstract

ABSTRACT 2, 3-Diaryl imidazolium salts, represented by 1 and 2, reacted with 2- ethanolamine or ethylenediamine to produce 2-aryl oxazolines or imidazolines 5–8 respectively. Their hydrolysis resulted in ring-opened ethylenediamine derivatives 9 and 10. The reduction of 1 and 2 produced partially reduced imidazolidines 11, 12 and 11 reacted further with tryptamine to provide 2, 3, 4, 9-tetrahydro-1-phenyl 1 H-pyrido [3, 4-b] indole, ...
