Nitrile-ketenimine tautomerism in substituted alkylidenemalonitriles and alkylidenecyanoacetates. Characteristic uv absorption band was written by Kasturi, T. R.;Sharma, V. K.;Srinivasan, A.;Subrahmanyam, G.. And the article was included in Tetrahedron in 1973.Electric Literature of C10H10N2O2 The following contents are mentioned in the article:
The uv spectra of several alkylidenemalononitriles and -cyanoacetates showed a band around 355 nm indicating the presence of ketenimine tautomers. The malononitriles added H2O and EtOH to give the corresponding pyridine derivatives This study involved multiple reactions and reactants, such as 1-Hydroxy-3-oxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitrile (cas: 52903-71-6Electric Literature of C10H10N2O2).
1-Hydroxy-3-oxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitrile (cas: 52903-71-6) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines. Isoquinoline-type alkaloids show biological activities similar to those of morphinane-, protoberberine-, and benzophenanthridine-type alkaloids.Electric Literature of C10H10N2O2
