Synthesis of 3-selanyl-isoflavones from 2-hydroxyphenyl enaminones using trichloroisocyanuric acid (TCCA): a sustainable approach†
Abstract
We hereby present an original and sustainable synthetic methodology for the synthesis of 3-selanyl-isoflavones from 2-hydroxyphenyl enaminones and diorganoyl diselenides. The reaction is promoted in a one-pot manner by the greener reagent trichloroisocyanuric acid and employs ethanol as a solvent under mild conditions. Using this protocol, 22 examples of 3-selanyl-isoflavones were prepared in 34%–95% yields.
