Transition-Metal-Free Base-Controlled C?N Coupling Reactions: Selective Mono Versus Diarylation of Primary Amines with 2-Chlorobenzimidazoles

Herein, a base-controlled protocol was developed for the C?N coupling of primary amines and 2-chlorobenzimidazoles, affording a handful of secondary or tertiary amines in a selective fashion. Moreover, this protocol was realized under transition-metal-fre

Palladium-Catalyzed Ligand-Free C-N Coupling Reactions: Selective Diheteroarylation of Amines with 2-Halobenzimidazoles

2-Aminobenzimidazoles are widely present in a number of bioactive molecules. Generally, the preparation of these molecules could be realized by the mono-substitution of 2-halobenzimidazoles with amines. However, rare examples were reported for the di-subs

Highly effective procedure for introduction of amino group into the 2-position of imidazole ring

Procedures for the preparation of 2-amino- and 2-arylaminobenzimidazoles were developed, and one of the efficient procedure was applied to the synthesis of preclathridine A, a marine imidazole alkaloid isolated from a sponge.

CONDENSED DERIVATIVES OF BENZAZOLES. 1. SYNTHESIS OF 6- AND 5-SUBSTITUTED BENZIMIDAZOQUINAZOLIN-12-ONES

6(5)H-Benzimidazoquinazolin-12-one was obtained in high yield by condensation of benzimidazole-2-sulfonic acid with anthranilic acid.Methods for the introduction of substituents selectively into the 5 and 6 positions of this heterocycle were develo

While base induced ring closure of 1-phenyl>-3-phenylthioureas 1 had furnished the corresponding type 2 dihydro-3,1,6-benzothiadiazocine derivatives rather than the isomeric hexahydro-1,3,6-ben

Photochemical Elimination of Molecular Nitrogen from Phenyl-Substituted 1,4-Dihydro-5-imino-5H-tetrazoles. Products of Phenyl-Substituted Tris(imino)methane Diradicals

The reaction of 5-(methylthio)tetrazolium salts 11 with primary amines produces the phenyl-substituted 5-iminotetrazoles 7b - h.In contrast to the results of the electron impact-induced fragmentation in the mass spectrometer, irradiation of the 5-iminotet
