Abstract: An efficient base‐promoted synthetic approach has been developed for the synthesis of benzo[ b ]naphthooxepinones from (3‐(acetylphenoxy)prop‐1‐yn‐1‐yl)benzaldehydes. The transformation proceeds via a base‐mediated 7‐ exo‐dig cyclization, followed by intramolecular aldol condensation and subsequent dehydration, resulting… read more here.
