Vinyl radicals were generated from 3-iodoflavones under a mercury lamp and tandem cyclization reactions occurred with five-membered heteroarenes entailing two consecutive C-C bond formations to synthesize benzo[e]chromeno[2,3-g]indol-13(1H)-one derivatives. The tandem cyclization reactions worked in acetonitrile without any additives such as transition metals, ligands and oxidants, giving rise to a broad variety of novel polycyclic xanthone frameworks in good yield under mild and environmentally friendly reaction conditions.
Multi-Step synthesis by using modular flow reactors: The preparation of Yne-Ones and their use in heterocycle synthesis

"Chemical Equation Presented" Multi-step in flow: The palladium-catalysed acylation of terminal alkynes for the synthesis of yne-ones as well as their further transformation to various heterocycles in a continuous-flow mode is presented. Furthermore, an extension of the simple flow configuration that allows for easy batch splitting and the generation of a heterocyclic library is described (see scheme).
Synthesis of 3-iodo derivatives of flavones, thioflavones and thiochromones

, p. 565 - 567 (2007/10/02)
The title compounds, 2-aryl-3-iodo-4H-1-benzopyrans and 2-alkyl or 2-aryl-3-iodo-4H-1-benzothiopyrans, were prepared by reaction of the corresponding heterocyclic derivatives with the iodine-cerium(IV) ammonium nitrate system under mild conditions. The scope and proposed mechanism of the reaction were also demonstrated.
