N2  - Deoxykojic acid (1) reacts with two benzyne molecules to afford 9-methyl-7-phenoxy-5,9-dihydro-5,9-epoxy-6H-benzocyclohepten-6-one (2) in 33% yield. Maltol (5) reacts with three molecules of benzyne to afford (4b&#945;,5&#946;,10&#946;,11a&#945;)-10-methyl-11a-phenoxy-4b,5,10,11a-tetrahydro-5,10-epoxy-11H- benzo&#91;a&#93;benzo&#91;3,4&#93;cyclobuta&#91;1,2-d&#93;cyclohepten-11-one (6a) in 36% yield.
