A convenient method for highly diastereoselective synthesis of bexagliflozin 7a and its carbon-13 labeled analogue 7b was developed. The main feature is the stereoselective reduction of 16 catalyzed by BF3·OEt2. Furthermore, the cocrystallization skill was firstly used for the purification of bexagliflozin and its analogue. The carbon-13 labeled bexagliflozin 7b was firstly prepared in five steps and
开发了一种方便的方法,用于非对映选择性合成贝格列净7a及其碳13标记的类似物7b。主要特征是BF 3 ·OEt 2催化的16的立体选择性还原。此外,共结晶技术首先用于纯化贝格列净及其类似物。碳13标记的贝格列净7b首先是从市售的d-葡萄糖酸内酯-[ 13 C 6 ]分五个步骤制备的,化学总产率为57%。
