Azeotropic reflux chromatography (in which the eluent is continuously recycled by means of refluxing) was used to separate a mixture of spiroketal intermediates in the scale-up synthesis of spongistatin 1, leading to an improved separation and an approximately 35-fold reduction in the amount of solvent used.
使用共沸回流色谱(通过回流方式持续循环洗脱溶剂)分离了海绵素1的放大合成过程中一混合物中的螺环中间体,从而改善了分离效果,并将所用溶剂量减少了约35倍。
