Fused Azolium Salts XVIII [1]. Synthesis and Reactivity of a Novel Fused Heteroaromatic System: [1,2,3]Triazolo[1,5-b]isoquinolinium Salts
摘要:
Oxidative cyclization of 3-isoquinolyl ketone hydrazones afforded the novel tricyclic heteroaromatic [1,2,3]triazolo[1,5-b]isoquinolinium salts. The reactivity of the ring system towards nucleophiles proved to be regioselective. Secondary amines induced ring opening of the pyridine moiety, forming a triazolyl substituted benzaldehyde derivative; sodium borohydride afforded partially reduced derivatives of the parent compound.
