studies not only enrich the tandem reaction design concerning the asymmetric catalytic assembly of a chiral all-carbon quaternary stereocenter contained in the densely functionalized hydrocarbazole synthons but also manifest the potential for the application of the asymmetric catalysis based on the para-dienone chemistry in asymmetric synthesis of natural products.
通过有机催化对映选择性去对称化,设计并开发了一种前所未有的螺环对二烯酮酰亚胺的不对称催化串联氨解/氮杂-迈克尔加成反应。已经针对两种天然夹竹桃科生物碱 (+)-deethylibophyllidine 和 (+)-limaspermidine 的不对称全合成探索了基于这种关键串联方法的统一策略。本研究不仅丰富了稠密功能化的烃咔唑合成子中手性全碳四元立体中心的不对称催化组装的串联反应设计,而且展示了基于对二烯酮化学的不对称催化应用的潜力。天然产物的不对称合成。
