A highly efficient, two-stage, continuous-flow synthesis of vitamin D3 from provitamin D3 was achieved. The developed method afforded the desired product in high yield (HPLC-UV: 60%, isolated: 32%) and required neither intermediate purification nor high-dilution conditions.
实现了从
维生素 D3 到
维生素 D3 的高效、两阶段、连续流合成。所开发的方法能以高产率(HPLC-UV:60%,分离:32%)获得所需的产品,并且既不需要中间纯化,也不需要高稀释条件。
