An efficient synthesis of the taxane-AB-fragment with a spiro-cyclopropyl group 2 was accomplished. The synthetic strategy toward this AB-fragment involved a cyclopropanation of hydroazulenone 1, a Grignard addition, and an acid catalyzed cyclopropylcarbinyl-rearrangement.
我们完成了带有螺环丙基 2 的紫杉烷-AB-片段的高效合成。这种 AB 片段的合成策略包括氢氮杂环烯酮 1 的环丙烷化、格氏加成和酸催化环丙基甲酰重排。
