(-)-Akagerine (1) was synthesized in an efficient and stereocontrolled fashion from the readily available (1S,2R)-cyclohexenedimethanol monoacetate 4. Key steps were the cleavage of the C(17)/C(18) bond of 14a and the regio- and stereoselective cyclization of the dialdehyde 16 to give the tetracyclic skeleton of akagerine.
(-)-赤霉素A₁ (1) 由易于获得的 (1S,2R)-环己二烯二甲醇单乙酸酯 4 通过高效且具有立体控制的方式合成。关键步骤包括 14a 中 C(17)/C(18) 键的裂解,以及 1,5-二甲醛 16 的区域选择性和立体选择性环化,从而形成赤霉素的四环骨架结构。
