Short and efficient syntheses of two diastereomeric cyclopentane segments present in most jatrophanediterpenes 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.
