An efficient, formal enantioselective synthesis of (+)- and (−)-pauciflorol F has been achieved using a recently introduced oxazolidinone controlled torquoselective Nazarov reaction. The absolute stereochemistry of pauciflorol F and its biosynthetic precursors has been unambiguously confirmed using X-ray crystallography.
使用最近引入的恶唑烷酮控制的对甲苯二酚的纳扎罗夫反应,已经实现了对(+)-和(-)-古朴三醇F的高效,正式对映选择性合成。使用X射线晶体学已明确地证实了紫杉醇F及其生物合成前体的绝对立体化学。
