fused bicyclic polyfunctional compounds containing a highly hydroxylated pyran ring starting from commercially available methyl glucopyranoside and adopting a RCM annulation approach. The versatile α,β-unsaturated ketone group was introduced on the newly formed ring and, as an example of the potential of these polyfunctionalized building blocks, a tetracyclic compound was synthesized through a Diels–Alder
我们从市售的甲基吡喃葡萄糖苷开始,采用 RCM 环化方法合成了含有高度羟基化吡喃环的稠合双环多官能化合物。在新形成的环上引入了通用的 α,β-不饱和酮基团,作为这些多官能化结构单元潜力的一个例子,通过狄尔斯-阿尔德环加成反应合成了四环化合物。
