In present work, an efficient and direct method for the synthesis of hexahydrochromeno[4,3-b]pyrrolo[2,1-a]isoquinolines is reported. This method involves ®T3P mediated oxidation of alcohols to aldehydes followed by [3+2] cycloaddition to afford hexahydrochromeno[4,3-b]pyrrolo[2,1-a]isoquinolines with good yields.


C-H Functionalization, ®T3P, [3+2] Cycloaddition, Chromene, Isoquinolines
