The reaction of 4-(3,4-dimethoxyphenyl)-5-aminopyrazoles 7A–D with aromatic and heterocyclic aldehydes in strong acidic media (trifluoroacetic or formic acid) has been studied. initial azomethine derivatives 8 undergo cyclization similar to the Pictet–Spengler condensation form intermediate 4,5-dihydroisoquinolines 9 which readily dehydrogenate giving 5-aryl(heteroaryl)-pyrazolo[3,4-c]isoquinoline 10 as final products. Whereas for benzaldehyde its this one-pot synthesis presents a convenient...

Abstract The convenient one pot synthesis of pyrazolo[3,4‐ c ]isoquinolines 1 from 5‐aminopyrazoles 2 and paraformaldehyde in formic or trifluoroacetic acids is described.
Sodium 3,5-bis(hydroxyimino)-1-methyl-2,4,6-trioxocyclohexanide C7H5N2NaO5 (I) has been isolated as the only product of reaction nitrosation methylphloroglucinol. The structure titled compound determined from single crystal X-ray diffraction data. hydrated C7H5N2NaO52.5H2O crystallizes in monoclinic space group C2/c, with a(?) 16.408(3); b(?) 12.446(3); c(?) 13.716(3); (o) 126.34(3). planar organic anion exists a triketo-dihydroxyimino form C–O and C–N distances 1.220(2) to 1.271(2) ?...
Reaction of α,α-dihalo-β-oxoaldehydes with diaminofurazan in acetonitrile affords unexpected 20-membered macrocycles.
Ten new complexes of 2,4,6–trihydroxy-3-methyl benzoic acid (methylphloroglucinol, L1) and 2,4,6–trihydroxy (phloroglucinol, L2) are isolated in the solid state, their formulae were detected.The spectroscopic methods indicate that coordination L1 L2 to metallic ions occurs through one O-atom deprotonated carboxylic group an O atom non-deprotonated neighboring hydroxy-group (bidentate chelating coordination). The schemes structure proposed.The complex formation solution is studied, constants...
