C-glycosides via BF3·Et2O promoted coupling of organotrifluoroborates and glycosyl fluorides is reported. The application of this method was further demonstrated by the concise and efficient total synthesis of (+)-varitriol in only seven steps.
据报道,通过BF 3 ·Et 2 O促进了有机三
氟硼酸酯和糖基
氟化物的偶联,采用了温和,立体选择性和快速的方法访问炔基和
烯基C-糖苷。该方法的应用通过仅七个步骤的简明有效的全合成(+)-varitriol进一步得到了证明。
