Isobenzofurans (IBF)s have seen widespread use in the synthesis of both natural products and polycyclic aromatic hydrocarbons. There are few examples that have two IBF entities linked in a fused aromatic ring system. Here we present the synthesis and

We have examined a series of 1,3-dihydro-1-isobenzofuranamines that exist in an imine/hemiaminal ring-chain tautomerism. The tautomeric free energies are rationalized in terms of electronic and steric effects. A series of compounds bearing substituen

Arylisobenzofurans can be generated from hemiaminal precursors derived from the reaction of ortho-lithiated benzyl alcohol with 1,3- and 1,4-dicyanobenzene electrophiles. The bis(hemiaminal) products so formed give adducts formally derived from 1,4-
