Synthesis of benzonorbornadienes: regioselective benzyne formation.

J. Org. Chem. 66(9) , 2932-6, (2001)

This report details the synthesis of several benzonorbornadienes by Diels--Alder cycloaddition of cyclopentadiene derivatives with substituted benzyne intermediates, which were generated by low-temper...
