Kenny, Rajesh S.,Mashelkar, Uday C.
, p. 1367 - 1369 (2006)
A facile and effective method for the synthesis of some benzothiazole derivatives is described. The method involves the action of aryl aldehyde and o-aminothiophenol in acetic acid resulting into in situ formation of the thiol substituted Schiffs base and

A simple synthesis of 2-arylbenzothiazoles and its application to palladium-catalyzed Mizoroki-Heck reaction
Kawashita, Yuka,Ueba, Chigusa,Hayashi, Masahiko
, p. 4231 - 4233 (2006)
A variety of 2-arylbenzothiazoles were prepared by the direct reaction of 2-aminobenzenethiol and aryl aldehydes by the aid of activated carbon (Shirasagi KL or Darco KB) under oxygen atmosphere. 2-Pyridylbenzothiazole, thus obtained, was proved to work as an efficient ligand in palladium-catalyzed Mizoroki-Heck reaction.
Nano-Titania-Supported Sulfonic-Acid-Catalyzed Synthesis of 2-Arylbenzothiazole Derivatives under Solvent Free Conditions
Amoozadeh, Ali,Azadeh, Rahmat Allah,Rahmani, Salman,Salehi, Mehdi,Kubicki, MacIej,Dutkiewicz, Grzegorz
, p. 1874 - 1883 (2015)
Nano-titania-supported sulfonic acid (n-TSA) has been used as an efficient, inexpensive and reusable heterogeneous nano catalyst for synthesis of 2-arylbenzothiazole derivatives under solvent free condition. The reaction works very well, with good to exce
Microwave-assisted synthesis of benzothiazole derivatives using glycerol as green solvent
Zhang, Xia-Zhong,Zhou, Wen-Jun,Yang, Min,Wang, Jin-Xian,Bai, Lin
, p. 489 - 491 (2012)
A rapid method has been developed for the synthesis of benzothiazoles via the condensation of 2-aminothiophenol with aldehydes under CEM-focused microwave irradiation conditions. The reaction used glycerol as a green solvent without any catalyst, renderin
Synthesis of fostedil (diethyl 4-(2-benzothiazolyl)benzylphosphonate) from N-acylimidates
Harizi, Abdallah,Zantour, Hedi
, p. 1883 - 1891 (2004)
Fostedil (diethyl 4-(benzothiazol-2-yl) benzylphosphonate) 7 has been synthesized efficiently by treatment of 2-(4-bromomethylphenyl) benzothiazole 6 with triethylphosphite. The latter (6) has been prepared by bromation of benzothiazole 3c. N-acylimidates 1(a-d) react with 2-aminobenzenethiol 2 to lead to the corresponding benzothiazoles 3(a-d) after elimination of primary amide 5. The structure of these products have been unequivocally confirmed by means of IR, 1H, 13C, and 31P NMR spectroscopy and mass spectra.
Direct C—H Bond Activation of Benzoxazole and Benzothiazole with Aryl Bromides Catalyzed by Palladium(II)-N-heterocyclic Carbene Complexes
Kalo?lu, Murat,Kalo?lur, Nazan,?zdemir, ?smail
, p. 837 - 844 (2018)
Herein, we report that a series of novel palladium(II)-NHC complexes (NHC=N-heterocyclic carbene) were synthesized. The structures of all novel complexes were characterized by 1H NMR, 13C NMR, FT-IR spectroscopy and elemental analysis techniques. These palladium(II)-NHC complexes were tested as efficient catalysts in the direct C—H bond activation of benzoxazole and benzothiazole with aryl bromides in the presence of 1 mol% catalyst loading at 150 °C for 4 h. Under the given conditions, various aryl bromides were successfully applied as the arylating reagents to achieve the 2-arylbenzoxazoles and 2-arylbenzothiazoles in acceptable to high yields.
Yttrium-catalyzed heterocyclic formation via aerobic oxygenation: A green approach to benzothiazoles

The YCl3-catalyzed aerobic oxidative cyclization reaction for the synthesis of benzothiazoles has been developed. This method provides a practical, effective and green synthetic approach to benzothiazoles which are important units in many biologically active compounds.
