4. Treatment of phthalan with excess Li metal in the presence of 4,4'-Di-tert-butyl biphenyl , B21470, results in opening of the furan ring. Sequential introduction of two different electrophiles can be effected in the resulting bis-benzylic species, consequently phthalan can be regarded as an o-xylene dianion synthon. This approach provides a convenient access to diols and hydroxy acids which can be readily dehydrated to benzo-fused 6- or 7-membered cyclic ethers or lactones: Tetrahedron, 51, 3351 (1995); see also: J.
