Abstract

The reaction of dihydrolipoic acid (DHLA) with 5-hydroxy-1,4-naphthoquinone (juglone) gives rise to the novel naphtho[1,4]dithiepine derivs. through ring expansion of an unstable spirocyclic 1,3-dithiane intermediate, which was isolated and completely characterized. Reported herein is also the characterization of novel reaction products of DHLA with other naphthoquinones and the extension of the study to the spirocyclic adduct formed by reaction with a representative 2-substituted naphthoquinone.
