The total synthesis of raistrickindole A has been achieved, thereby confirming the proposed structure as an -hydroxylated DKP. In the first but less selective approach, the DKP was built up by cyclization of a diastereoisomerically mixed -hydroxylated dipeptide. In the second approach, the same DKP was constructed stereoselectively by the intramolecular Mitsunobu reaction of a hydroxamic acid. The synthesis was completed by a stereoselective oxidative cyclization.
瑞斯特林吲哚 A 的全合成已经实现，从而证实了所提出的结构为 - 羟基化 DKP。在第一个但选择性较低的方法中，通过非对映异构体混合 - 羟基化二肽的环化构建了 DKP。在第二种方法中，通过羟肟酸的分子内 Mitsunobu 反应立体选择性地构建了相同的 DKP。通过立体选择性氧化环化完成了合成。
