Enantiomerically pure β-necrodol (1) and its 1-epimer 16 have been synthesized starting from aldehyde 5. The two key steps are an asymmetric conjugate addtion/Mannich reaction tandem (1012) and a type-II-magnesiumene cyclization/oxidation sequence (141 + 16).
对映体纯的β-necrodol(1)及其1 -epimer 16已从醛5开始合成。这两个关键步骤是不对称共轭加成/曼尼希反应串联(10 12)和II型镁烯环化/氧化序列(14 1 + 16)。
