The first total synthesis of (+)-lycoflexine (1), a constituent of Lycopodium clavatum var. inflexum , has been accomplished in eight steps with 13% overall yield. Our synthesis covers four one-pot reactions, including a tandem Sakurai/aldol sequence, a novel hydroboration/oxidation procedure, a deprotection/transannular Mannich reaction, and as a highlight, a tandem catalysis cascade combining an
第一次全合成 (+)-lycoflexine (1),Lycopodium clavatum var. 的一种成分。inflexum 已分八步完成,总产率为 13%。我们的合成涵盖四个一锅反应,包括串联 Sakurai/aldol 序列、新型硼氢化/氧化程序、脱保护/跨环曼尼希反应,以及作为亮点的串联催化级联反应,该串联催化级联结合了烯炔闭环复分解和选择性氢化。
