A facile approach for the synthesis of flavans was developed by employing a BF3·Et2O-catalyzed pyran cyclization in an aprotic polar solvent as a key step, by which concise total syntheses of (±)-7-hydroxy-3′,4′-methylenedioxyflavan (1) and (±)-4′-hydroxy-7-methoxyflavan (2), two naturally occurring flavans, were achieved.
