新型螺双二氢茚二酚衍生物的合成
Chinese Journal of Synthetic Chemistry（2015）
Abstract
螺双二氢茚二酚(SPINOL)与N-溴代丁二酰亚胺经溴代反应制得6,6'-二溴-螺双二氢茚二酚(1);1与叔丁基二甲基硅基三氟甲磺酸(rBSOTf)经醚化反应得6,6'-二溴-7-羟基-7'-叔丁基二甲硅氧基-1,1'-螺二氢茚(2);SPINOL经羟基保护后与碘甲烷经双甲基化反应制得6,6 '-二甲基-7,7'-双(1-甲氧甲氧基)-1,1'-螺二氢茚(4);4经脱保护后再与TBSOTf经醚化反应合成了6,6'-二甲基-7-羟基-7'-叔丁基二甲硅氧基-1,1'-螺二氢茚(6).2和6为新化合物,其结构经1H NMR,13C NMR和HR-ESI-MS表征.
