Abstract Among the natural tetramic acids with a decalinoyl part, signermycin B is unique because it contains a cis‐decalin. In this paper, we demonstrate that the cis‐decalin section of signermycin B can be accessed by an anionic oxy‐Cope rear

An efficient installation of a 3,7-dimethylocta-2,6-dien-1-yl (geranyl or neryl) side chain at the C(1) position of a xanthone core by utilizing an anion-accelerated aromatic oxy-Cope rearrangement is described. Experiments revealed that this uncommo

Charge-accelerated rearrangements present interesting challenges to enantioselective catalysis, due in large part to the competing requirements for maximizing reactivity (ion-pair separation) and stereochemical communication. Herein, we describe appl

Diaddition of alkenyllithium to 1,2-diones induce dianionic oxy-Cope rearrangements. As 1,2-diones some 1,2-diarylethane-1,2-diones were treated with (4,5-dihydrofuran-2-yl)lithium. The reaction, which took place at -78 °C, stereoselctively afforded

Tandem anionic oxy-Cope rearrangement/radical oxygenation reactions provide δ,ϵ-unsaturated α-(aminoxy) carbonyl compounds, which serve as convenient precursors to diverse compound classes. Functionalized carbocycles are accessible by very rare al
