Abstract
An effective approach for the highly selective synthesis of selenium-containing (E)-N-propenolquinazolinones via an FeCl3·6H2O mediated cascade reaction of propargyl quinazoline-4-yl ethers and diselenides has been developed. Mechanistic investigations revealed that the reaction of FeCl3 and (PhSe)2 generates, in situ, the electrophilic species PhSe[FeCl4]·6H2O, which triggers the cascade reaction.
