A synthetic study of eudesmanolides was performed utilizing a Suzuki coupling reaction of tris(4-methylfuran-3-yl)boroxine (6) as the pivotal step. The other key reactions involved Friedel–Crafts acylation, Wacker–Tsuji reaction and aldol condensation. In this Ring C→BC→ABC approach, a model compound 3 towards the synthesis of eudesmanolides 11,13-dihydrotubiferin (1) and artogallin (2) was realized
使用三(4-甲基呋喃-3-基)环硼氧烷(6)的Suzuki偶联反应作为关键步骤,进行了对马鞭草内酯的合成研究。其他关键反应包括Friedel-Crafts酰化反应,Wacker-Tsuji反应和羟醛缩合反应。在这种C→BC→ABC环的方法中,实现了合成大地马里内酯11,13-二氢tubiferin(1)和Artogallin(2)的模型化合物3。在另一个模型研究中,还获得了五元类似物4。
