1,8-萘二基双(二氯硼烷)衍生的手性刘易斯酸是一种新型的双齿刘易斯酸,被发现是不对称Diels-Alder反应的催化剂。利用衍生自氨基酸的手性配体,已经用环戊二烯和各种α,β-不饱和醛实现了一系列对映选择性。这种新型的不对称双齿催化剂的一些机制方面已经解决。
Chiral Lewis acids derived from 1,8-Naphthalenediylbis(dichloroborane), a novel bidentate Lewis acid, have been found to be active catalysts for the asymmetric Diels-Alder reaction. Utilizing chiral ligands derived from amino acids, a range of enantioselectivities have been achieved with cyclopentadiene and various alpha,beta-unsaturated aldehydes. Some mechanistic aspects of this novel asymmetric bidentate catalyst have been addressed.
