An enantioselective epoxidation of tryptophols followed by an intramolecular epoxide opening reaction was realized by chiral vanadium catalysts derived from C2 symmetric bis-hydroxamic acid (BHA) ligands. 3a-Hydroxyfuroindoline derivatives with up to 89% yield and 90% ee were obtained under mild reaction conditions.

Abstract

Chiral N-triflyl phosphoramide was found an efficient catalyst for the enantioselective Friedel-Crafts alkylation reaction of 4,7-dihydroindole with β,γ-unsaturated α-keto esters. In the presence of 5 mol% of the optimized catalyst, various pyrrolo[1,2-a]indoles were obtained in excellent enantioselectivity, moderate yields and up to 3:1 diastereoselectivity based on the one-pot synthesis including the Friedel-Crafts alkylation reaction and the subsequent p-benzoquinone oxidation.

Abstract

This Review summarizes the development of catalytic asymmetric dearomatization (CADA) reactions. The CADA reactions discussed herein include oxidative dearomatization reactions, dearomatization by Diels–Alder and related reactions, the alkylative dearomatization of electron-rich arenes, transition-metal-catalyzed dearomatization reactions, cascade sequences involving asymmetric dearomatization as the key step, and nucleophilic dearomatization reactions of pyridinium derivatives. Asymmetric dearomatization reactions with chiral auxiliaries and catalytic asymmetric reactions of dearomatized substrates are also briefly introduced. This Review intends to provide a concept for catalytic asymmetric dearomatization.

Abstract

Dieser Aufsatz fasst die bisherigen Entwicklungen auf dem Gebiet der katalytischen asymmetrischen Desaromatisierungen (CADAs) zusammen. Die hier diskutierten katalytischen asymmetrischen Desaromatisierungen umfassen oxidative Desaromatisierungen, Desaromatisierungen durch Diels-Alder- und verwandte Reaktionen, alkylierende Desaromatisierungen elektronenreicher Arene, Übergangsmetall-katalysierte Desaromatisierungen, Kaskadensequenzen mit asymmetrischer Desaromatisierung sowie nucleophile Desaromatisierungen von Pyridinium-Derivaten. Zudem werden kurz asymmetrische Desaromatisierungen mithilfe chiraler Auxiliare sowie katalytische asymmetrische Reaktionen mit desaromatisierten Substraten eingeführt. Ziel dieses Aufsatzes ist es, ein Konzept für die asymmetrische Desaromatisierung zu liefern.
