A 6-step synthesis of the naphthoicacidcomponent of the natural antitumor agent neocarzinostatinchromophore is described. The synthetic route employs 4-bromo-3-methylanisole as the starting material, proceeds in 31–37% yield for the 6 steps, and features as the key step a photocyclizationreaction that is an interesting variant of known photocyclizationreactions of stilbenes and phenylbutadienes

the diol 84 with the naphthoicacid 13 followed by selective cleavage of the chloroacetate protective group in situ to furnish the naphthoicacid ester 85 in 80% yield; and elimination of the tertiary hydroxyl group within intermediate 88 using the Martin sulfurane reagent (79% yield). Reductive transposition of the product epoxy alcohol (58) then formed neocarzinostatinchromophore aglycon (2, 71% yield)
