[Figure not available: see fulltext.] Straightforward method for the synthesis of pyrrolo[1,2-b]cinnolines starting from 2-nitrobenzaldehydes and 2-methylfurans has been elaborated. The key steps of the process are oxidative furan ring opening with diazon

A new approach to highly functionalized quinolines is proposed. This approach is based on the electrophilic recyclization of 2-[2-(acylamino)benzyl] furans under the Bischler-Napieralski reaction conditions. Georg Thieme Verlag Stuttgart. New York.

New representatives of chelate-type titanium(IV) salicylideneaniline complexes with bis(5-methyl-2-furyl)methyl substituents in the aniline fragment are synthesized. In the presence of poly(methylalumoxane), these complexes catalyze ethylene and propylene polymerization. The effect of the position of substituents in the ligands on the activities of the catalysts is studied. High-molecular-weight linear polyethylene (M w ≈ 172200-300000, M w/M n ≈ 2-3) and high-molecular-weight atactic elastic polypropylene (M w ≈ 1000000, M w/M n ≥ 7.0) are obtained.
Furan ring opening-indole ring closure: Synthesis of furo[2′, 3′:3,4]-cycloheota[1,2-b]indolium chlorides

A new synthetic approach to furo[2′,3′:3,4]cyclohepta[1,2-b] indolium chlorides is elaborated starting from 2-acetylaminoaryldifurylmethanes or 2-aminoaryldifurylmethanes under treatment with methanolic HCl solution. The reaction proceeds in three steps: recyclization, intramolecular cyclization, and disproportionation. In this case the furan ring takes part in building up both pyrrole and seven-membered rings. The same salts can be obtained directly from 2-acetylaminobenzaldehydes and 2-methylfuran under similar conditions without isolation of corresponding 2-acetylaminoaryldifurylmethanes.
