Selective Synthesis and Cycloaddition Reactions of New Azomethine Imines Containing a 1,2,4‐Triazine Ring.

Abstract

Selective Synthesis and Cycloaddition Reactions of New Azomethine Imines Containing a 1,2,4-Triazine Ring. -The reaction of triazines (I) with aldehydes (II) gives stable iminium salts (III) on treatment with a base, they afford tetra-and pentacyclic aza heterocycles in the presence of dipolarophiles. -(GROF, C.; HEGEDUS, G.; RIEDL, Z.; HAJOS*, G.; EGYED, O.; CSAMPAI, A.; KUDAR, V.; STANOVNIK, B.; Eur.
