The reaction of flavones with 2,4,4,6-tetrabromo-2,5-cyclo hexadienone(1) gave the corresponding 3-bromoflavones under the mild reaction condition. Flavones containing easily oxidizable functional groups were also brominated without deleterious oxidation
Transformation of 1-thioflavonoids by oxidation and dehydrogenation
Somogyi
, p. 1857 - 1872 (2007/10/03)
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.
