The one-step interaction of 1H-benzotriazoles with maleimides in melt at elevated temperatures has resulted in benzotriazolylsuccinimides. According to spectroscopy data, benzotriazolylsuccinimides obtained contain both major (benzotriazol-1-yl)-succinimide residue and minor (benzotriazol-2-yl)-succinimide residue. An effect of substituents in the initial reagents on the fine splitting of carbon peaks in 13C NMR spectrums of benzotriazolylsuccinimides is discussed. The influence of structure of benzotriazolylsuccinimides on their crystallinity degree is also discussed.

Abstract A practical BF3·OEt2-catalyzed regioselective 1,2-addition or 1,4-hetero-Michael addition of oxygen, sulfur, and nitrogen nucleo philes to maleimides has been developed for the synthesis of alkyl fumarate derivatives or 3-su
Photochemistry of benzotriazoles: Generation of 1,3-diradicals and intermolecular cycloaddition as a new route toward indoles and dihydropyrrolo[3,4-b]indoles

Irradiation of benzotriazoles 1a-e at λ = 254 nm in acetonitrile solution generated the corresponding 1,3-diradicals which underwent intermolecular cycloaddition with maleimides to afford the corresponding dihydropyrrolo[3,4-b]indoles and with acetylene derivatives to afford indoles as the major products. This offers an interesting and simple access to such ring systems of potential synthetic and biological interest. The structures of the photoproducts were established spectroscopically and by single crystal X-ray crystallography.
