AbstractA new class of (2R,4S)-N-aryl-4-hydroxy-1-(2,2,2-trifluoroacetyl)pyrrolidine-2-carboxamide compounds was synthesized by a facile one-pot reaction of trans-4-hydroxy proline and trifluoroacetimidoyl chlorides in the presence of \(\hbox TiO}_2}\)-nanoparticles as a catalyst and sodium bicarbonate as a base. Synthesized compounds showed cytotoxicity with \(\hbox IC}_50}\) values of 15.3–70
抽象的通过反式-4-羟基的一锅反应,合成了新型的(2R,4S)-N-芳基-4-羟基-1-(2,2,2-三氟乙酰基)吡咯烷-2-羧酰胺化合物。在\(\ hbox TiO} _ 2} \)-纳米颗粒作为催化剂和碳酸氢钠作为碱的存在下,脯氨酸和三氟乙酰亚胺基氯化物。合成的化合物显示出细胞毒性,\(\ hbox中IC} _ 50} \)的15.3-70.3值 \(\ upmu \ hbox中M} \)对K562(智人,人)细胞。研究结果为一锅合成反式-4-羟基脯氨酸基N-(2,2,2-三氟乙酰化)化合物提供了一种有价值的方法。而且,这些化合物作为抗菌剂和抗真菌剂显示出显着的药物活性。 图形概要
