An efficient synthesis of the Stemona alkaloid (−)-sessilifoliamide J (1) in 12 steps and 7.7% overall yield from the known building block 8 is presented. The synthesis features the Corey lactonization reaction and a highly diastereoselective α-methylation reaction to build the spiro-lactone moiety.
提出了一种从12个步骤中有效合成花粉生物碱(-)-sessilifoliamide J(1)和总产率为7.7%的已知结构单元8。该合成具有科里内酯化反应和高度非对映选择性的α-甲基化反应以构建螺内酯部分的特征。
