Transformation of 1-thioflavonoids by oxidation and dehydrogenation

Article abstract of DOI:10.1080/00397919908086175

Simple, efficient and selective new one-step transformations with DDQ, IBDA and I₂/DMSO are presented for the dehydrogenation of thioflavanone (1α), as well as the oxidized (1c) and halogenated (1d) derivatives. Ring- contraction reactions of the 1-oxide 1b and 1d leading to the formation of the benzothiophen derivatives 3a and 5, respectively, are also described.
