The Ziegler intermediate, useful for the total synthesis of forskolin, was synthesized in 10 reaction steps starting from commercially available α-ionone. This highly efficient synthesis relies on the success of two consecutive highly regio- and stereoselective rearrangements. The current synthesis has not only established an efficient synthetic route to access the Ziegler intermediate but it has also
从总的α-紫罗兰酮开始,在10个反应步骤中合成了可用于福斯克林的全合成的Ziegler中间体。这种高效的合成依赖于两个连续的高度区域和立体选择性重排的成功。当前的合成不仅建立了进入齐格勒中间体的有效合成途径,而且还为毛喉素的结构优化铺平了道路。
