## Abstract The ^1^H and ^13^C NMR data for 3‐azabicyclo[3.3.1]nonanes with OH and OMe substituents at C‐6 and C‐9 were measured using 1D (DEPT) and 2D (COSY, HSQC, HMBC, NOESY) experiments. Comparison of this NMR data illustrates the effects of stereochemistry and substitution at these positions.

Abstract
^13^C NMR spectra of 3‐benzylflavones, 3‐benzylideneflavanones, 3‐benzyl‐4‐thioflavones, 3‐benzyl‐1‐thioflavones, 3‐benzyl‐1,4‐dithioflavones and 3‐benzyl‐1‐thioflavone‐1,1‐dioxides were analysed and correlated to evaluate the consequences of the replacement of oxygen with sulphur.

A set of 3-alkylaminoacroleins (R1NHCHxCHCHxO, R1 \ alkyl) were studied by 13C and 1H NMR spectroscopy in solutions of di †erent solvents and, for the simplest representative of the series, 3methylaminoacrolein, at di †erent temperatures. The equilibrium solutions of these compounds consists of mixt
A series of 14 3-substituted 4-oxoquinolones with or without a substituent (methyl, ethyl) in position 1 were prepared. Literature and measured data were used to study the inÑuence of the substituent on the shifts of carbon atoms of these compounds, which are model compounds for antibacterial drugs
The uC NMR spectra of three mesoionic 1,2,3-triazol-4-ylacetamides and two 1,2,3-triazol-4-ones were determined, and an evaluation of the shifts in relation to their mesoionic structure was made.
