Abstract

Stereoselective total synthesis of the C(40)-diacetylenic carotenoid alloxanthin (1) and the C(31)-acetylenic apocarotenoid triophaxanthin (2) was accomplished by Wittig condensation of C(10)-dialdehyde 20 or C(16)-keto aldehyde 19, respectively, with C(15)-acetylenic tri-n-butylphosphonium salt 12.

摘要

通过 C(10)-二醛 20 或 C(16)-酮醛 19 与 C(15)-炔基三丁基膦盐 12 的 Wittig 缩合反应,分别完成了 C(40)-二乙酰基类胡萝卜素 alloxanthin (1) 和 C(31)-炔基类胡萝卜素 apocarotenoid triophaxanthin (2) 的立体选择性全合成。
