摘要

Thermolyses of the 1-carbomethoxy-1-alkenyloxybenzocyclobutenes 4a–d produced the dihydronaphthalenes 7a–d via chemoselective electrocyclic reaction of Eo- quinodimethanes in good yields. Then, 7a, b, d were easily converted to the 2-naphthol 9 (R1= R2= H) by sequential dehydrogenation and deprotection. The method of conversion developed here has been successfully applied to an efficient synthesis of the ...
