- This paper indroduced the synthesis methed of norfloxacin by borane compound.The product had high quality and good yield(62 %). 介绍了硼螯化合物合成诺氟沙星的方法,收率高(总收率62%25以上)。
- Asymmetric borane reduction of prochiral ketones is a good process to the synthesis of enantiomerically enriched secondary alcohols. 硼烷对前手性酮的不对称还原是合成手性仲醇的重要方法。
- The asymmetric reduction of ketosulfone with borane catalyzed by oxazaborolidine is computed by means of the semi-empirical MNDO method. 对恶唑硼烷催化前手性酮砜不对称还原反应进行了半经验MNDO研究。
- The borane modified by chiral oxazoborolidines enantioselectively reduced aliphatic and aromatic ketones to yield sec-alcohols with 100% yield and medium to high optical yields. 硼烷-手性(口恶)唑硼烷-还原体系能将脂肪酮和芳香酮还原为仲醇,化学还原收率町达100%25,光学收率也比较高。
- Using 10 as the catalyst, six prochiral ketones were reduced enantioselectively with borane and the results were compared with those with 1,1- diphenylprolinol as catalys. 用10催化6种前手性酮的不对称硼烷还原反应,其结果与(S)-二苯基脯氨醇催化的同一反应的结果进行了对比。
- Compared with the pure pitches, pyridine borane modified pitches had higher softening points, carbon yields and PI fraction content at the same reaction conditions. 在同一反应条件下,体系有无吡啶硼烷,所得结果有显著差别。吡啶硼烷改性系列的软化点、残炭值及PI组份的含量均明显高于纯沥青系列。
