Catalytic asymmetric Diels–Alder reaction of α-amino-o-quinodimethane with α,β-unsaturated aldehydes was achieved with high diastereo- and enantioselectivities in the presence of l-proline, which acts as a promoter to generate the quinodimethane from the corresponding precursor as well as a chiral catalyst for the enantioselective Diels–Alder reaction.
在l-脯氨酸存在下,具有高非对映选择性和对映选择性的α-氨基-邻-喹二甲烷与α,β-不饱和醛的催化不对称Diels-Alder反应,该促进剂起促进剂的作用,从相应的前体生成喹二甲烷以及对映选择性Diels-Alder反应的手性催化剂。
