Trifluoromethylation of the acyclic derivative of D-lyxose, 3, with trifluoromethyltrimethylsilane in the presence of tetrabutylammonium fluoride yielded a mixture of trifluoromethyl adducts, 5a and b, which was converted to 6,6,6-trifluoro-L-fucose 9a and 6-deoxy-6,6,6-trifluoro-D-altrose 9bvia selective oxidation of the primary hydroxy group involving treatment of the trimethylsiloxy derivatives, 7a and b, with
在四丁基氟化铵的存在下,用三氟甲基三甲基硅烷将D-赖糖3的无环衍生物进行三氟甲基化,生成三氟甲基加合物5a和b的混合物,将其转化为6,6,6-三氟-L-岩藻糖9a和6-通过选择性氧化伯羟基来脱氧-6,6,6-三氟-D - altrose 9b,包括用柯林斯试剂处理三甲基甲硅烷氧基衍生物7a和b。
