developed a one-pot cyclization cascade with high chemocontrol and diastereoselectivity. The sequence generates two cycles, three carbon–carbon bonds, and an all-carbon quaternary center in a highly convergent process. Functionalized polyhydroquinolines and congeners can be accessed from commercially available amino acids. This versatile and robust strategy was applied to the synthesis of (±)-Δ7-mesembrenone
取代的聚氢喹啉是药物和生物活性天然产物中普遍存在的骨架核心。作为获取该基序的新途径,我们成功开发了具有高化学控制和非对映选择性的一锅环化级联。该序列在高度收敛的过程中产生两个循环、三个碳-碳键和一个全碳四元中心。官能化的聚氢喹啉和同系物可以从市售氨基酸中获得。这种多功能且稳健的策略被应用于 (±)-Δ 7 -mesembrenone 的合成。
