cyclopentane derivative was obtained in high yield. The intermediary azazirconacycle was treated with D 3 O + , I 2 or t-BuNC to give the desired deuterated, iodinated or formylated product, respectively, at the vinyl position in good yield. Transmetalation of zirconacycle to CuCl was carried out and then allyl chloride was added to give an allylated compound in good yield. Selective bond fission of
成功实现了锆介导的炔亚胺的分子内环化。当在MgSO 4 存在下由炔醛和伯胺制备的粗亚胺在室温下用Cp 2 ZrBu 2 处理数小时时,以高收率获得环戊烷衍生物。中间氮杂环酮用D 3 O + 、I 2 或t-BuNC处理,分别在乙烯基位置以良好收率得到所需的氘代、碘代或甲酰化产物。进行锆环向CuCl的金属转移,然后加入烯丙基氯,以良好的收率得到烯丙基化的化合物。氮杂环的锆-氮键的选择性裂变是通过用酰卤处理氮杂环来实现的,得到N-酰化的乙烯基锆化合物。
