Triple Benzannulation of Naphthalene via a 1,3,6-Naphthotriyne Synthetic Equivalent. Synthesis of Dibenz[a,c]anthracene.

A new synthesis of dibenzo[a,c]anthracene (4) is described that features the generation, from tetrabromo-bis-triflate 1 and phenyllithium, of a 1,3,6-naphthotriyne (2) synthetic equivalent that is trapped with 3 equiv of furan to form Diels-Alder tris-adduct 3. A subsequent two-step deoxygenation of 3 represents the first synthesis of dibenz[a,c]anthracene (4) that involves a tandem aryne Diels-Alder cycloaddition-deoxygenation strategy.

Oxidative coupling of phenols and phenolic ethers. Part 4. Synthesis of dibenz[d,f]azonines and a dibenz[d,f]azacine, via direct coupling

Two series of amides, the N-phenethylphenylacetamides (9) and the bisphenethylamides (11), including diphenolic monophenolic, and non-phenolic types, were treated with a range of one-electron oxidants. With the tetramethoxy-derivative (11e) intramolecular coupling yielded a dibenzazonine (16) in 36% yield. Similar oxidation of the homologue (18) gave a dibenzazecine (19) in 60% yield.

Epoxy derivatives of aromatic polycyclic hydrocarbons. The synthesis of dibenz[a,c]anthracene 10,11-oxide and its metabolism by rat liver preparations.

The synthesis of dibenz[a,c]anthracene 10,11-oxide is described. The oxide was unstable and was rapidly decomposed with cold mineral acid into a mixture of 10- and 11- hydroxydibenz[a,c]anthracene. The oxide was converted by rat liver microsomal preparations and homogenates into a product that is probably 10,11-dihydro-10,11-dihydroxydibenz[a,c]anthracene and which was identical with the metabolite formed when dibenz[a,c]anthracene was metabolized by rat liver homogenates. The oxide did not react either chemically or enzymically with GSH. 10,11-Dihydrodibenz[a,c]anthracene and 10,11-dihydrodibenz[a,c]anthracene 12,13-oxide were both metabolized by rat liver preparations into trans-10,11,12,13-tetrahydro-10,11-dihydroxydibenz[a,c] anthracene and the oxide was converted chemically into this dihydroxy compound, and it reacted chemically but not enzymically with GSH. In the alkylation of 4-(p-nitrobenzyl)pyridine, the ;K-region' epoxide, dibenz[a,h]anthracene 5,6-oxide, was more active than either dibenz[a,c]anthracene 10,11-oxide or 10,11-dihydrobenz[a,c]anthracene 12,13-oxide.

THE SYNTHESIS OF DIBENZ[a,c][1,3]CYCLOHEPTADIENE - 5,7-DIONE

The synthesis of dibenz[a, c][1,3]cycloheptadiene-5,7-dione (I), a new member of the dibenz[a,c][1,3]cycloheptadiene (II) series, has been accomplished by (1) the condensation of diethyl diphenate and ethyl acetate with alkaline catalysts, (2) the reaction of diphenoyl chloride and sodiomalonic ester, and (3) the condensation of diphenic anhydride and malonic ester with zinc chloride. In addition to the (I), these reactions afford comparable amounts of 2,21-diacetyl biphenyl (XIII). It has been possible to establish the identity of (I) from the carbonyl and enolic derivatives and products obtained in reactions of hydrolysis, oxidation, and reduction.
