A simple and safe route to the D-xylone-1,4-lactone derivative 3, a key intermediate for the synthesis of the spiroketal fragment in calyculin A (1) has been explored without the use of hazardous diazomethane on a large scale.
在没有大规模使用危险的重氮甲烷的情况下,已经探索了一种简单而安全的途径来合成D-木酮-1,4-内酯衍生物3,这是在calyculin A(1)中合成螺环酮片段的关键中间体。
