substituted Δ3‐1,2,3‐triazolines can be prepared by reaction of triarylvinyl Grignard reagents with functionalized organic azides. The heterocycles are fluorescent in the solid state, and—depending on the substituents—they can display aggregation‐induced emission. Upon oxidation, the triazolines form stable radical cations with altered photophysical properties. Therefore, they represent rare examples of

of potent specific HIV-1 inhibitory compounds is described. The lead compound in the series, N-(2-phenethyl)-N'-(2-thiazolyl)thiourea (1), inhibitsHIV-1 RT using rCdG as the template with an IC50 of 0.9 microM. In MT-4 cells, compound 1 inhibitsHIV-1 with an ED50 of 1.3 microM. The 50% cytotoxic dose in cell culture is > 380 microM. The chemical structure-activityrelationship (SAR) was developed
N-(2-azidophenyl)azolium salts were easily prepared and reacted with copper(I) in conditions allowing the formation of NHC complexes. In these conditions, the formation of benzimidazo-fused heterocycles occurred in catalytic, efficient and...

N-Acyl indolines were obtained unexpectedly from a consecutive cyclization of iminophosphorane in refluxing xylene or 1,2-dichlorobenzene in good yields. This new approach provides an efficient and direct access to the biologically important indolines which are further oxidizable to indoles and oxindoles.
A process for the addition of an azide function to an organic compound in which process a mixture is prepared by adding an epoxide-derivative of the organic compound and an alkali metal azide salt to a solvent is described. The mixture is heated to a reaction temperature at which the epoxide-derivative and the azide can react to form an azide derivative of the organic compound. An amount, near equimolar to the epoxide derivative, of a (1-6C)alkyl-(2-4C)carboxylic acid ester having a boiling point above the reaction temperature is added to the mixture before and/or during the reaction.
