Summar~~: Intermolecular 2 + 2 aldehyde-ketene cycloaddition, followed by Lewis acid induced intramolecular ring opening of the 2-oxetanone product have been used to prepare tetrahydrofuran and tetrahydropyran ring systems. Among lactones, 2-oxetanones are characterized by their readiness to underg

Treatment of 2-cyclopropylazobenzenes with concentrated sulfuric acid affords the intramolecular N-and C-alkylation products. Treatment of azobenzenes with trifluoroacetic acid results in quantitative rearrangement to arylindazoles via the intermediate formation of acid-stable indazolium ions. It is
An efficient and convenient one-pot synthesis of 4-aryl-2-methylsulfanyl-6,7-dihydro-5H-dibenzo[a,c]cycloheptene-1carboxylate 3a-n has been delineated and illustrated through carbanion induced ring transformation of 6-aryl-3-carbomethoxy-4methylsulfanyl-2H-pyran-2-ones 1 with benzosuberone 2.
