A four-step synthetic approach to substituted linear and angular benzofurocoumarins is described. Starting from 5-methoxyresorcinol, this approach afforded good yields of benzopsoralen (7), benzoangelicine (8), and benzoallopsoralen (11), which bear easily hydrolysed methoxy groups and thus allow access to other substituted compounds with potential as photochemotherapeutic agents.
