A continuous flow photooxygenation of 7-aminothieno[3,2-c]pyridin-4(5H)-ones to produce 7-iminothieno[3,2-c]pyridine-4,6(5H,7H)-diones has been developed, utilizing ambient air as the sole reactant. N-H Imines are formed as the major products, and excellent functional group tolerance and conversion on gram-scale without the need for chromatographic purification allow for facile late-stage diversification
连续流光氧化7-氨基噻吩并[3,2- c ]吡啶-4(5 H)-产生7-亚氨基噻吩并[3,2 - c ]吡啶-4,6(5 H,7 H)-二酮已经开发出利用环境空气作为唯一反应物的技术。N- H亚胺形成为主要产物,并且出色的官能团耐受性和克级转化率(无需色谱纯化)可实现氨基噻吩并吡啶酮支架的简便后期分散。几种类似物在体外具有对癌症相关蛋白酪氨酸磷酸酶PTP4A3的有效抑制作用,并且SAR支持探索性对接模型。
