## Abstract Herein, we describe the synthesis and complete assignment of the ^1^H and ^13^C NMR chemical shifts of a series of antimicrobial 4‐arylamino‐3‐nitrocoumarin derivatives based on a combination of ^1^H and ^13^C NMR, ^1^H‐^1^H‐COSY, NOESY, HSQC and HMBC experiments. Conformational effects

✦ Synopsis
One- and two-dimensional NMR experiments were used for the unambiguous assignment of the 1H and 13C NMR chemical shifts of 3,3-diisopentenyl-N-methyl-2,4-quinoldione and five novel reaction derivatives.

## Abstract Two new 3,4‐secofriedelanes, 3,4‐seco‐28‐hydroxyfriedelan‐3‐oic acid (1) and 3,4‐secofriedelan‐3‐oic acid (2), were isolated from the leaves of __Austroplenckia populnea__ (Celastraceae). The structures were established by 2D NMR spectroscopic techniques (COSY, HMQC, HMBC and NOESY). Co
The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d
## Abstract The ^1^H NMR spectrum of naphtho [1′,2′:4,5]thieno[2,3‐__c__]quinoline is highly congested because all the protons are in an aromatic environment, and the structure of the molecule is nearly symmetric. With this in mind, the assignment of the ^1^H and ^13^C NMR spectra of this compound
