The rhodium(III)‐catalyzed C−H amidation and subsequent C−N bond formation reaction of indolines with aryl and alkyl isocyanates at room temperature are reported. These transformations allow the generation of N‐aroylurea functionality at the C7‐position of indolines, which is known as a crucial scaffold found in biologically active molecules. In addition, the synthesis of pyrroloindolidione derivatives
据报道,铑(III)催化的CH酰胺化反应和随后在室温下吲哚与芳基和烷基异氰酸酯的CN键形成反应。这些转化使得在吲哚啉的C7位上生成N芳基脲官能团,这是在生物活性分子中发现的至关重要的支架。此外,还通过顺序的C6酰胺化反应和C7酰胺化的二氢吲哚的分子内环化描述了吡咯烷吲哚酮衍生物的合成。评估了所有合成产物对人前列腺腺癌细胞(DU145),人乳腺癌细胞(MCF-7)和三阴性人类乳腺癌细胞(MDA-MB-231)的体外细胞毒性作用。值得注意的是,化合物4 d和发现具有线性烷基侧链的4 e具有高度的细胞毒性,与抗癌药阿霉素和顺铂的阳性对照相当。
