Аннотация: Novel β-arylethylamines bearing 5-pyrazolone substituent in the ortho-position of aryl moiety were obtained by the hydrazine-induced recyclization of 1-(alkoxycarbonyl-methylidene)-1,2,3,4-tetrahydroisoquinolines. These amines can exist in a highly unstable betaine form in the solid phase.

Ключевые слова: natural β-arylethylamines, 1,2.3.4-tetrahydroisoquinolines, hydrazine, recyclization, 5-pyrazolones, internal salts, metastable structures.
