regioselective 1,3-dipolar cycloaddition. The present methodology capitalized on trichloroisocyanuric acid (TCCA) as a safe and ecological oxidant and chlorinating agent for the in-situ conversion of aldehydes to nitrile oxides in the presence of hydroxylamine hydrochloride, under ultrasound activation. These nitrile oxides could be engaged in 1,3-dipolar cycloaddition reactions with various alkene to
在本研究中,按照一锅两步方案,我们通过高度区域选择性的1,3-偶极环加成合成了新型磺酰胺-异恶唑啉杂化物( 3a-r )。本方法利用三氯异氰尿酸(TCCA)作为一种安全且生态的氧化剂和氯化剂,在盐酸羟胺存在下,在超声活化下将醛原位转化为氧化腈。这些腈氧化物可以与各种烯烃进行 1,3-偶极环加成反应,得到目标磺酰胺-异恶唑啉杂化物 ( 3a-r )。评估了后者对模型白血病细胞系(慢性粒细胞白血病,K562 和早幼粒细胞白血病,HL-60)的抗肿瘤活性。
