The synthesis of 3,6-epoxy carotenoids cucurbitaxanthin A 1, cycloviolaxanthin 2 and capsanthin 3,6-epoxide 3, was accomplished via the C15-3,6-epoxides 20e and 20f, prepared by the regioselective ring opening of the 3-hydroxy-5,6-epoxides 10e and 10f.
3,6-epoxy 类胡萝卜素葫芦黄素 A 1、环紫黄素 2 和辣椒黄素 3,6-epoxide 3 是通过 C15-3,6-epoxides 20e 和 20f 合成的,C15-3,6-epoxides 20e 和 20f 是由 3-hydroxy-5,6-epoxides 10e 和 10f 通过区域选择性开环制备的。
