An improved green procedure for the synthesis of 2-aryl- and 2-hetarylbenzothiazoles by condensation of equivalent amounts of 2,2′-diaminodiphenyldisulfides or 2-aminothiophenols and various aromatic aldehydes in PEG 200/400 undermicrowaveirradiation has been developed. This method allows the synthesis of 2-arylbenzothiazoles in high yields and with high purity regardless of the state of the starting
A convenient synthesis of 2-(2-(difluoromethoxy)aryl)benzo[d]thiazoles from 2- (o-hydroxyaryl)benzothiazoles and commercially available ethyl difluoroiodoacetate (ICF2CO2Et) is described. The transformation was amenable to a one-pot, sequential three-component protocol from o-hydroxybenzaldehyde, o-aminothiophenol, and ICF2CO2Et promoted by KOH. Additionally, some of the prepared compounds exhibited
描述了由2-(邻-羟基芳基)苯并噻唑和可商购的二氟碘乙酸乙酯(ICF 2 CO 2 Et)方便地合成2-(2-(二氟甲氧基)芳基)苯并[d]噻唑的方法。变换为适合于从一釜,顺序三组分协议ö羟基苯甲醛,ø -aminothiophenol,和ICF 2 CO 2的Et促进由KOH。另外,一些制备的化合物对人卵巢癌细胞显示出有希望的活性。
