Short and efficient syntheses of two diastereomeric cyclopentane segments present in most jatrophane diterpenes were achieved. Key steps are a stereoselective C-2 elongation, an RCM, and a hydroboration reaction. An orthogonal protecting group methodology makes these segments useful building blocks for diterpene synthesis.
实现了大多数麻风树二萜中存在的两个非对映异构环戊烷链段的短而有效的合成。关键步骤是立体选择性 C-2 延伸、RCM 和硼氢化反应。正交保护基方法使这些片段成为二萜合成的有用构件。
