A series of 3,4-dihydroisoquinoline-3-carboxylic acid derivatives were synthesised and tested for their free-radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH·), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radi

In this study, we found that a recently discovered ECD-Raman effect dominated over the natural Raman optical activity in a series of atropisomeric naphthalenediimides, and we investigated the kind of information about the molecular structure that cou

Raman optical activity (ROA) spectra recorded for a chiral naphthalene diimide derivative (nBu-NDI–BINAM) dissolved in a series of solvents exhibit strong solute to solvent induced chirality with: (1) dominating bands of solvents, (2) nBu-NDI–BIN

We present first evidence of a spontaneous alkylation of the 2′-deoxycytidine by potential topoisomerase I inhibitors from camptothecins family. The 7-ethyl-9-(N-morpholino)methyl-10-hydroxycamptothecin and the 7-ethyl-9-(N-pyrrolidinyl)methyl-10-h

The mechanism of alkylation of the 2′-deoxyadenosine (dA) by potential topoisomerase I (Top I) inhibitors, from the camptothecin family, is described in water and in DMSO-d6. The products of the reactions depend on the solvent; however in both case

A reaction of Grignard reagents with an optically pure N -sulfinylimine derived from methyl 2-formylbenzoate yields enantioenriched isoindolinones and tert -butyl sulfoxides. The products are formed by the addition of the nucleophile to N -sulfinylim
