Abstract

mCPBA-mediated intramolecular oxidative annulation of ortho-crotyl or cinnamyl arylaldehydes provides chroman, coumaran, isochroman, and tetrahydrobenzo[ c]oxepine under different reaction conditions. This research investigates the reaction conditions for facile and efficient transformation.
