Outlandish: The spiroketal embedded in spirastrellolide F methyl ester is a daring site for ring closure, yet it has allowed the power of catalytic alkyne scission and activation to be showcased (see scheme). An improved strategy for the introduction of the labile side chain was also developed.
奇异的:螺菌灵内酯F甲酯中嵌入的螺环酮是一个大胆的闭环位点,但它却可以显示出催化炔烃裂解和活化的能力(请参阅方案)。还开发了引入不稳定侧链的改进策略。
