Diastereoselective aza-cope rearrangement-mannich cyclizations of conformationally mobile iminium cations
… a Lewis-acid catalyzed, diastereoselective aza-Cope rearrangement— Mannich cyclization (ACM) to form acyl pyrrolidines from conformationally mobile substrates. Earlier studies from our lab have shown that substituted acyl pyrrolidines can be synthesized with diastereoselectivity of 50:1 …

Advancements in the diastereoselective synthesis of acyl pyrrolidines via the tandem aza-Cope—Mannich cyclization pathway
… a Lewis-acid catalyzed, diastereoselective aza-Cope rearrangement— Mannich cyclization to form acyl pyrrolidines from conformationally mobile substrates. In earlier studies from our lab, Brønsted acid-catalyzed reactions to form the same acyl pyrrolidines resulted in diastereoselectivities …

Development of a microwave-assisted epoxide aminolysis and investigation of the aza-cope rearrangement--mannich cyclization for alkaloid synthesis
… and other methods were used to investigate the aza-Cope rearrangement—Mannich cyclization. We proposed that this procedure could be used to produce compounds we could modify and transform into several alkaloids.</p>

Part 1. Diaziridinium Ions: First Reported Synthesis and Reactivity Studies. Part 2. Tropylium Ion Mediated alpha-Cyanation of Amines. Part 3. Multicatalytic Synthesis of Complex Tetrahydrofurans
… an application of this new oxidant towards an aza-Cope rearrangement. Finally, we report a multicatalytic method that uses bismuth(III) triflate to catalyze a nucleophilic addition to an aldehyde followed by hydroalkoxylation to generate highly functionalized tetrahydrofuran rings, a motif that …

Inhibitor studies on para-aminobenzoic acid synthase.
… and chorismate analogues was performed using the aza-Cope and oxy-Cope rearrangements of oxygen-alkylated hydroxybenzoates and N-alkylated aromatic amines. The organic synthesis of an inhibitor containing vinyl fluoride functionality has been the focus of previous studies. The biosynthesis of …
