标题:通过脂肪酸的全分子引入非对称α,ω-双官能化长链化合物
摘要:α,ω-双官能化长链化合物a-(ch 2)n-B是有价值的中间体和单体.然而,迄今为止,具有两个不同官能团(a!=b)的不对称化合物只能通过多步传统有机合成法获得.我们通过油酸衍生物链深处的双键的烷氧基羰基化异构化一步报告了它们的反应生成.与底物中酰胺,腈和酰亚胺官能团的相容性可形成具有高线性选择性(约90%)和不对称二酯,酯-酰胺,酯-腈和酯-(n的转化率(70-96%)-亚胺),其中这些官能团末端连接到>=17亚甲基单元链上.这些产品进一步提供了从这些ab单体中获得羧酸酯,醇酯和氨基酯以及聚合物的途径.通过在胺碱存在下使用不含酸添加剂的pd(II)催化剂前体,完全扰乱了a和b官能团的不良酯交换反应(<0.1%)被抑制.
