lagunensis, contains 24-propylcholesterol, a potentially useful biomarker for this organism. The stereochemical configuration at C-24 was determined through synthesis using the Johnson orthoester Claisen rearrangement. Both (24R)- and (24S)-24-propylcholesterol, as well as (24R)- and (24S)-Δ22 24-propylcholesterol, were synthesized and characterized. The naturally occurring isomer was found to be (
导致“得克萨斯棕色潮”的藻类,即金黄色藻,含有24-丙基胆固醇,对这种生物来说可能是有用的生物标记。使用强生原酸酯克莱森重排通过合成确定C-24处的立体化学构型。两者(24 - [R )-和(24小号)-24-propylcholesterol,以及(24 - [R )-和(24小号)-Δ 22 24 propylcholesterol,被合成和表征。发现天然异构体为(24 R)-24-丙基胆固醇。
