A benzodiazepine derivative of formula I, or a pharmaceutically acceptable salt thereof: ##STR1## wherein: (a) R.sup.4 is an alkyl, cycloalkyl or aryl group. (b) R.sup.10 is chosen from halo, OH, CH.sub.3, OCH.sub.3, NR.sup.11 R.sup.12, NO.sub.2, NHCHO, CO.sub.2 H and CN, and R.sup.11 and R.sup.12 are independently selected from H and alkyl (C.sub.1 -C.sub.5) or together NR.sup.11 R.sup.12 form a cyclic structure II, ##STR2## wherein a is 1-6; and (c) R.sup.2 is an aromatic 5- or 6-membered, substituted or unsubstituted heterocycle containing at least two heteroatoms of which at least one is nitrogen. These compounds are gastrin and/or CCK-B receptor antagonists.

building blocks in medicinal chemistry and chemical industry. A palladium-catalyzed direct α-C(sp3) heteroarylation of ketones under microwave irradiation is developed and reported in this study. Under optimized conditions, twenty-eight (28) heteroarylated ketones were prepared in this study to demonstrate the substrate scope of this reaction. The ground-state optimized structure of Pd(0) active catalyst

An efficient synthesis of nitrogen-containing heterocycles via Pd-catalyzed tandem allylic alkylation and dearomatization reactions was reported. In this reaction design, heteroarenes such as pyridines, pyrazines, and quinolines serve as bis-nucleophiles by installing a benzoyl group at the C2 benzylic position. With but-2-ene-1,4-diyl dimethyl dicarbonate as the bis-electrophile, the tandem Pd-catalyzed
据报道,通过Pd催化的串联烯丙基烷基化和脱芳香化反应可有效合成含氮杂环。在该反应设计中,杂芳烃如吡啶,吡嗪和喹啉通过在C2苄基位置安装苯甲酰基而用作双亲核试剂。以二碳酸二烯丁酯-1,4-二烷基二芳酯为双亲电子体,已开发了串联的钯催化苯甲酰基甲基取代的杂芳烃的分子间烯丙基烷基化/烯丙基脱芳香化反应。以中等至良好的产率获得了2,3-二氢吲哚嗪,6,7-二氢吡咯并[1,2- a ]吡嗪和1,2-二氢吡咯并[1,2- a ]喹啉衍生物。

The first Ir-catalyzed intramolecularasymmetricallylicdearomatization reaction of pyridines, pyrazines, quinolines, and isoquinolines has been developed. Enabled by in situ formed chiral Ir-catalyst, the dearomatized products were isolated in high levels of yield (up to 99% yield) and enantioselectivity (up to 99% ee). It is worth noting that the Me-THQphos ligand is much more efficient than other
已开发出第一个 Ir 催化的吡啶、吡嗪、喹啉和异喹啉的分子内不对称烯丙基脱芳构化反应。通过原位形成的手性 Ir 催化剂,脱芳构化产物以高产率(高达 99% 的产率)和对映选择性(高达 99% ee)分离。值得注意的是,对于吡嗪和某些喹啉的脱芳构化,Me-THQphos 配体比其他测试的配体更有效。进行了脱芳构化反应的机理研究,结果表明了以形成喹啉作为关键中间体的替代方法的可行性。机理研究结果使该反应成为 Reissert 型反应化学中尚不为人知的类型。此外,
