(diisopropyl)carbamate group, generated from a Hoppe allylation reaction, was easily transformed either into the corresponding (Z)-vinyl phosphate or (Z)-vinyl triflate function in good yield and high selectivity. It was also shown that the result- ing (Z)-vinyl triflate compound could be utilized successfully in palladium-catalysed coupling reactions with vinyl-, phenyl- and acetylenic tin derivatives, without
由 Hoppe 烯丙基化反应生成的 (Z)-乙烯基 (二异丙基) 氨基甲酸酯基团很容易以良好的收率和高选择性转化为相应的 (Z)- 磷酸乙烯酯或 (Z)- 三氟甲磺酸乙烯酯官能团。还表明,所得的 (Z)-三氟甲磺酸乙烯酯化合物可以成功地用于钯催化的与乙烯基、苯基和炔属锡衍生物的偶联反应,而不会损失双键的 (Z)-几何形状。 .
