inhibitory concentration assay confirmed retention of antimicrobial activity in many of these derivatives, while all compounds exhibited decreased xenoestrogen activity as determined by a combination of competitive enzyme linked immunosorbentassay (ELISA), proliferation, and estrogenreceptorbindingassay. Thus, these changes to the paraben scaffold have led to a multitude of paraben derivatives

Bromination of phenolic compounds without directly using molecular bromine possesses much importance. In this article an IrIII/CCl3Br-assisted single-step double functionalization of hydroxy benzaldehydes is reported. It involves simultaneous esterification of the aldehyde group and bromination of the aryl ring of phenolic aldehydes in one-pot. The reaction proceeds under mild conditions in the presence
不直接使用分子溴对酚类化合物进行溴化具有重要意义。本文报道了 IrIII/CCl3Br 辅助的羟基苯甲醛单步双官能化。它涉及在一锅中同时进行醛基酯化和酚醛芳环的溴化。在 445 nm 蓝光 LED 光的存在下,反应在温和条件下进行,以中等至良好的产率获得高度官能化的溴羟基苯甲酸酯。相比之下,Selectfluor 作为氧化剂只产生非溴酚酸酯。
