An efficient and general protocol for copper-catalyzed N-arylation of aliphatic amines and amino acids has been developed using aryliodides under mild conditions (coupling temperature at 25-35 degrees C). For the N-(o-nitrophenyl) amino acid derivatives, subsequent reduction of the nitro group in the presence of tin(II) chloride resulted in 3,4-dihydroquinoxalin-2(1H)-one derivatives in good yields
使用芳基碘化物在温和条件下(偶联温度为 25-35 摄氏度)开发了一种用于铜催化脂肪胺和氨基酸 N-芳基化的高效通用方案。对于 N-(o-硝基苯基) 氨基酸衍生物,随后在氯化锡 (II) 存在下还原硝基会以良好的产率得到 3,4-二氢喹喔啉-2(1H)-one 衍生物。
Effect of novel N-cyano-tetrahydro-pyridazine compounds, a class of cathepsin K inhibitors, on the bone resorptive activity of mature osteoclasts
activities of carbonitrile derivatives in the enzymatic activity of cathepsin K and their binding scores predicted using FlexX-Pharm docking program. The binding pattern of [1-(2-cyano-tetrahydro-pyridazine-1-carbonyl)-2-methy-propyl]-carbamic acid benzyl ester (8), one member of this series, was similar to that of the reference. In a bone pit formation assay, compound 8 was shown to dose-dependently
