A number of N-benzoylglycines (6), N-acetyl-N-phenylglycines (7), N-benzoyl-N-phenylglycines (8), and tricyclic N-acetic acids (9-12) were synthesized as analogues of the N-acylglycine-containing aldose reductase inhibitors alrestatin and 2-oxoquinoline-1-acetic acid. Derivatives of 6, which represent ring-simplified analogues of alrestatin, are very weak inhibitors of aldose reductase obtained from rat lens, producing 50% inhibition only at concentrations exceeding 100 microM. Compounds of series 7 were designed as ring-opened analogues of the 2-oxoquinolines. While these derivatives are more potent than compounds of series 6 (IC50S of 6-80 microM), they are less active than the corresponding 2-oxoquinolines. Analogues of series 8 were designed as hybrid structures of both alrestatin and the 2-oxoquinoline-1-acetic acids. These compounds are substantially more potent than compounds of series 6 and 7 and display inhibitory activities comparable to or greater than alrestatin or the 2-oxoquinolines (IC50S of 0.1-10 microM). Of the rigid analogues of 8, the most potent derivative is benzoxindole (12) with an IC50 of 0.67 microM, suggesting that fusion of the two aromatic rings of 8 in a coplanar conformation may optimize affinity for aldose reductase in this series.

reaction conditions for C–H functionalization. Protocols for the meta- and ortho-C–H iodination of aniline derivatives via formal C(sp2)–H/C(sp2)–I metathesis using 2-nitrophenyl iodides as mild iodinating reagents are reported herein. These protocols led to the production of a range of valuable iodinated aniline derivatives. These results demonstrate the potential of developing novel site-selective
