a concise and convergent route using methyl (R)‐lactate and (R)‐3‐methylcyclohexanone as chiral building blocks. Key steps of the synthesis are the stereocontrolled formation of the two quaternary stereocenters by diastereoselective 1,4‐conjugate addition and enolate alkylation reactions, and the construction of the furanonaphthoquinone skeleton by regioselective Diels–Alder reaction between a 1,3‐
通过使用(R)-乳酸酯和(R)-3-甲基环己酮作为手性结构单元的简洁且趋同的途径,实现了(+)-新海马酮的第一个全合成。合成的关键步骤是通过非对映选择性1,4-共轭加成和烯醇烷基化反应立体控制形成两个四级立体中心,以及通过1,3-双(三甲基甲硅烷基氧基)之间的区域选择性Diels-Alder反应构建呋喃萘甲醌骨架。 ‐1,3-二烯和溴醌。合成证明了天然新松香油酮的相对和绝对立体化学。
