基于2-(3,4-二乙氧基苯基)-5-氟苯并噻唑的有效和选择性的体外抗肿瘤特性,合成了一系列新的2-烷基/芳基苯并噻唑。苯并噻唑类似物的合成是通过在200°C的温度下以微波辐射1:1的邻氨基硫酚和烷基/芳基酰基乙腈的混合物进行的。产量非常好。所有产物均通过1 H nmr,13 C nmr和元素分析进行表征。
Suzuki-Miyaura coupling reactions of 2,6-dichlorobenzothiazole with arylboronic acids, promoted by microwave heating, efficiently produce 2-aryl-6-chlorobenzothiazoles in a highly regioselective manner. This process serves as the foundation for a simple method to rapidly construct 2-aryl-6-chlorobenzothiazole libraries. (c) 2006 Elsevier Ltd. All rights reserved.

A series of new 2-alkyl/arylbenzothiazoles has been synthesized on the basis of the potent and selective in vitro anti-tumor properties of 2-(3,4-diethoxyphenyl)-5-fluorobenzothiazole. The synthesis of benzothiazole analogs was achieved via microwave irradiation of a 1:1 mixture of o-aminothiophenol and alkyl/aryl acylacetonitriles at temperature of 200°C for 10 min. The yields are very good to excellent
