An enantioselective total synthesis of hamacanthin B (1) is described. This synthesis is based on the asymmetric synthesis of (S)-2-azido-(indol-3-yl)ethylamine 7, which is coupled with the 3-indolyl-alpha-oxoacetyl chloride 8 and subsequently used in a successful intramolecular Staudinger-aza Wittig cyclization to form the central dihydropyrazinone ring. The stereochemistry of naturally isolated hamacanthin
描述了对卵黄素B(1)的对映选择性全合成。该合成是基于(S)-2-叠氮基-(吲哚-3-基)乙胺7的不对称合成,它与3-吲哚基-α-氧代乙酰氯8偶联,随后用于成功的分子内Staudinger-氮杂维蒂希环化形成中心二氢吡嗪酮环。天然分离的卵黄素B的立体化学显示为(S)-构型。
