By using ambient air as the oxidant and malic acid as the promoter, a practical method for the preparation of 2-aminobenzothiazoles through visible-light-initiated cascade reaction of aromatic amines and KSCN in eco-friendly bis(methoxypropy)ether under metal-, hazardous additive-, photocatalyst-free conditions was established.

Abstract: A highly efficient and simple protocol for the preparation of 2-aminobenzothiazoles through the reaction of potassium thiocyanate and substituted anilines in the presence of nano-BF3/SiO2 as a reusable heterogeneous catalyst is described. In this method, all of the 2-amino-substituted benzothiazoles were obtained in high to excellent yields and short reaction times under mild conditions. The structures of the resulting products were characterized and confirmed by melting point, FT-IR, 1H NMR and 13C NMR techniques.

2-Aminobenzthiazole is a privileged scaffold with a range of biological activities. However, to date, an efficient protocol for the synthesis of this ring system using aniline as a starting material has been lacking. Herein, for the first time, we describe a highly efficient and mild protocol for the synthesis of 2-aminiobenzthiazole using NaICl Georg Thieme Verlag Stuttgart ? New York.

As a part of systematic investigation on synthesis and biological activities, some new derivatives of 2-ethyl-3-(substituted benzothiazole- 2′-yl)-[3H]-quinazolin-4-ones 3 have been synthesized, and the structures of the compounds were confirmed by elemental analysis and spectral data. The newly synthesized derivatives are then screened for anticonvulsant activity by maximal electroshock method. Copyright

experimental part, p. 985 - 993 (2012/01/05)
4-Phenyl-2H-pyrimido[2,1-b]benzothiazol-2-ones have been synthesized in quantitative yields by the reaction of 2-aminobenzothiazoles with alkynoic acid. The antimicrobial activity of the synthesized compounds was tested against bacterial species, Bacillus coagulans, Bacillus subtilis, Staphylococcus aureus, and Pseudomonas aeruginosa. The synthesized compounds have shown significant activity against microorganisms which can be correlated with the fused heterocyclic systems.
