Asymmetric Epoxidation of 1,4-Naphthoquinones Catalyzed by Guanidine–Urea Bifunctional Organocatalyst
An enantioselective nucleophilic epoxidation of 2-substituted 1,4-naphthoquinones in the presence of a newly developed guanidine–bisurea bifunctional organocatalyst with tert-butyl hydroperoxide (TBHP) as an oxidant is presented. 1,4-Naphthoquinones bearing substituents at C6, C7, and C2 were available for the reaction, and the corresponding epoxides were obtained with 88:12–95:5 er in 71–98% yields
Herein, we report a safe and economical multigramsynthesis of 6-fluoromenadione, an intermediate in the synthesis of novel biologically active agents. The key to this six-step sequence process involves the condensation of the readily available starting 4′-fluoropropiophenone and glyoxylic acid, a bromination–elimination sequence from 7-fluoro-3-methyltetral-1-one allowing aromatization of the naphthol
