The first total synthesis of (-)-calicoferol B (III) is described. The cyclozirconation product I, prepared in enantiomerically pure form, was converted into the CD ring chiron II. This was coupled with the aromatic A-ring, and then the side chain was constructed with control of relative and absolute configuration to complete the total synthesis of III. The first total synthesis of (-)-calicoferol B (1) is described. The cyclozirconation product 8, prepared in enantiomerically pure form, was converted into the CD ring chiron 6. This was coupled with the aromatic A-ring, and then the side chain was constructed with control of relative and absolute configuration to complete the total synthesis of 1.
描述了(-)-加利福罗醇B(III)的首次全合成。以对映体纯形式制备的环锆化产物I被转化为CD环手性中间体II。将其与芳香族A环偶联,然后构建侧链并控制相对和绝对构型以完成III的全合成。描述了(-)-加利福罗醇B(1)的首次全合成。以对映体纯形式制备的环锆化产物8被转化为CD环手性中间体6。将其与芳香族A环偶联,然后构建侧链并控制相对和绝对构型以完成1的全合成。
