Abstract
本发明涉及手性磷化合物及其过渡金属络合物,还涉及这些过渡金属络合物的应用,特别是在不对称合成中的应用。
Description
本发明涉及手性氮-磷化合物及其过渡金属络合物,还涉及这些过渡金属络合物的应用,特别是在不对称合成中的应用。
对映异构富化的(enantiomerically enriched)手性化合物是珍贵的用于制备农用化学品和药物的原料。不对称催化在此类对映异构富化的手性化合物合成中已得到很大的工业上的重视。
大量不对称合成领域的出版物清楚地表明,氮-磷化合物的过渡金属络合物非常适合用作不对称反应中的催化剂,特别是烯丙基取代反应、氢化反应和Heck反应(也参见Malkov等,Tetrahedron Letters,2001,42,3045-3048;Pfaltz等,Adv.Synth.Cat.,2003,345,33-44;Chelucci等,Tetrahedron,2001,57,9989-9996,Schleich,Helmchen,Eur.J.Org.Chem.,1999,2525-2521)。
至今为止已知的化合物的缺陷在于其制备过程复杂,需要若干阶段,并且中心配体结构的空间和电子变异困难,对于催化反应中较宽的底物范围只有很小的适用性。
因此仍然需要开发空间和电子性质易于改变的配体体系,并且该配体的过渡金属络合物作为催化剂,特别是在不对称合成中,不仅能够提供良好的对映选择性,而且能够提供良好的转化速率。
发明内容
