Indazoles are of considerable interest due to the broad variety of their biological activities.
This overview summarizes structures of pharmacologically interesting indazoles published …

A spectroscopic study of several ortho-hydroxy Schiff bases was carried out, and the
corresponding crystal structures were analyzed in order to identify their characteristic …

The benzotriazole fragment is known to behave as (1) an excellent leaving group,(2) an
electron-donating or an electron-withdrawing group,(3) an anion precursor, and (4) a radical …

The behavior of Schiff bases derived from 3-hydroxypyridin-4-carboxaldehyde and two N-
aminoheterocycles in acid media is described. 1H, 13C, 15N NMR chemical shifts establish …

This paper extends previous studies on hydrazones derived from hydroxyl naphthaldehydes
to aromatic N-aminoheterocycles (exemplified herein by triazole derivatives), in an attempt …

Abstract In 1 H and 13 C NMR spectra of N-substituted dimethylketimines chemical shifts of
protons and carbon atoms of the methyl groups in the cis-position with respect to the …

Abstract Schiff bases of 3‐hydroxypyridin‐4‐carboxaldehyde and l‐α‐amino esters as well
as those derived from the structurally related amines lacking the ester function have been …

The effect of complexation with Lewis acids on the tautomeric equilibrium of a derivative of
pyridoxal has been explored using density functional theory. Three complexation sites …

The present work includes the synthesis of different Schiff bases by the reaction of aniline
with benzaldehyde and its derivatives. These Schiff bases reacted with phenoxy acid …

В спектрах ЯМР 1 H и 13 С N-замещенных диметилкетиминов химические сдвиги
протонов и атомов углерода метильных групп в цис-положении относительно …
