Transformation Of 1-Thioflavonoids By Oxidation And Dehydrogenation

Transformation Of 1-Thioflavonoids By Oxidation And Dehydrogenation

Simple, efficient and selective new one-step transformations with DDQ, IBDA and I 2 /DMSO are presented for the dehydrogenation of thioflavanone (la), as well as the oxidized (1c) and halogenated (1d) derivatives. Ring-contraction reactions of the 1-oxide lb and Id leading to the formation of the be...

Zusammenfassung:Simple, efficient and selective new one-step transformations with DDQ, IBDA and I 2 /DMSO are presented for the dehydrogenation of thioflavanone (la), as well as the oxidized (1c) and halogenated (1d) derivatives. Ring-contraction reactions of the 1-oxide lb and Id leading to the formation of the benzothiophen derivatives 3α and 5, respectively, are also described.
