摘要:已经制备了带有磺酸基团的核壳氧化锆包覆磁铁矿纳米颗粒(纳米-Fe3O4@zro2-H3Po4),并将其用作一种有效的酸催化剂,用于通过 7-卤代-6 氟喹诺酮-3 羧酸与各种哌嗪衍生物和 (4Ar,7Ar)-八氢-1H-吡咯并[3,4-B] 吡啶.反应在普通水或磁化水作用作溶剂中进行.在最终结果中,纳米 Fe3O4@zro2-So3H 在两种形式的水中都表现出非常好的催化性能.然而,磁化水显示出更好的结果.因此,这种新方法在回流条件下,在作为绿色溶剂的水中以可接受的收率和简单的后处理过程迅速实现了合适的产品.此外,

摘要:The present invention provides a process for the preparation of racemic or chiral octahydro-6-(phenylmethyl)-1H-pyrrolo[3,4-b]pyridine of formula I, a key intermediate in the synthesis of moxifloxacin or its pharmaceutically acceptable salts. The process comprises reaction of racemic or chiral tetrahydro-6-(phenylmethyl)-1H- pyrrolo[3,4-b]pyridine-5,7(6H)-dione of formula II with a reducing agent, which is a mixture of two agents, that is mixture of dimethyl sulphate and sodium borohydride or aluminum chloride and sodium borohydride used in a molar ratio ranging from 1:1 to 1: 4, in the presence of a polar solvent at a temperature ranging from 15°C to 45°C 10 to obtain racemic or chiral octahydro-6-(phenylmethyl)-1H-pyrrolo[3,4-b]pyridine of formula I having purity ≥ 96%.
