项目摘要

We have synthesized epoxyquinol A, B, C and epoxytwinol A, by the biomimetic dimerization of 2H-pyran derivatives. The former three natural products were derived by the Diels-Alder reaction, while the latter was synthesized by the formal 4+4 cycloaddition reaction, which is a very rare reaction. We have investigated the reaction mechanism of this 4+4 cycloaddition via ab initio calculation and found that the reaction would proceed via a biradical mechanism. We have also synthesized several natural products with strong biological activities, such as lucilactaene, synerazol, pseurotin A, RK-805, fumagillol, FR65814, ovalicin, 5-demethylovalicin, EI-1941-1, EI-1941-2, EI-1941-3, panepophenanthrin, nikkomycin B, and fostriecin. During these syntheses, we developed several practical asymmetric reactions using oragnocatalysts such as direct aldol reaction in the presence of water, Mannich reaction, α-aminoxylation of carbonyl compounds, and Michael reaction.
通过2 H-吡喃衍生物的仿生二聚反应,合成了环氧喹啉A、B、C和环氧双酚A。前三种天然产物是通过Diels-Alder反应得到的,而后者是通过形式上的4+4环加成反应合成的,这是一个非常罕见的反应。通过从头计算研究了该4+4环加成反应的机理,发现该反应是通过双自由基机理进行的。我们还合成了几种具有较强生物活性的天然产物,如Lucilactaene、增效唑、假丝酵母素A、RK-805、烟曲霉醇、FR 65814、卵蒜素、5-去甲基缬蒜素、EI-1941-1、EI-1941-2、EI-1941-3、泛表菲、尼可霉素B和fostriecin。在这些合成中,我们开发了几个实用的有机催化不对称反应,如水存在下的直接羟醛缩合反应、Mannich反应、羰基化合物的α-氨氧基化反应和Michael反应。
