项目摘要

Chiral Lewis base coordinates to metallic center of metallic reagents and activates the reagent. Consequently, it is highly probable that stereochemical control of the reaction would be achieved by coordination of the chiral Lewis base to metal. However, the use of chiral Lewis base in the reaction is quite rare in the modern synthetic chemistry. This is clearly contrasted to the familiar use of chiral Lewis acid as activator as well as stereoconytoller.In the present research we focused on design, synthesis, and application of chiral Lewis base into asymmetric synthesis. Moreover, we applied the chiral Lewis base as a chiral catalyst in the reaction which can produce optically active compounds more than the equivalence of the chiral catalyst.As a result of the studies we developed quite promising reactions as shown below.1. Asymmetric synthesis of beta-lactam of more than 90% ee by the reaction of lithium ester enolate with imine in the presence of chiral amino ether catalyst.2. Catalytic asymmetric synthesis of highly optically active beta-lactam using catalytic amount of chiral amino ether.3. Catalytic asymmetric synthesis of amines of more than 90% ee by the reaction of organolithium with imines.These promising results may open a new world of synthetic organic chemistry and its application to the industrial production.
手性Lewis碱与金属试剂的金属中心配位并活化试剂。因此,很有可能通过手性路易斯碱与金属的配位来实现反应的立体化学控制。然而,手性Lewis碱在反应中的应用在现代合成化学中是相当少见的。这与通常使用的手性Lewis酸作为活化剂和立体共聚物形成了鲜明的对比。在本研究中,我们主要研究了手性Lewis碱的设计、合成及其在不对称合成中的应用。此外,我们还将手性Lewis碱作为手性催化剂应用于该反应,可以得到比手性催化剂更多的光学活性化合物。手性氨基醚催化下烯醇酸锂与亚胺反应合成90%以上的β-内酰胺。利用催化量的手性氨基醚催化不对称合成高光学活性的β-内酰胺。有机锂与亚胺反应催化不对称合成胺的含量在90%以上,有望开辟合成有机化学及其在工业生产中应用的新天地。
