Synthesis of Azulene-substituted Benzofurans and Isocoumarins via Intramolecular Cyclization of 1-Ethynylazulenes, and their Structural and Optical Properties

Org. Biomol. Chem., 2017, Accepted Manuscript DOI: 10.1039/C7OB02861J, PaperTaku Shoji, Miwa Tabaka, Sho Takagaki, Kota Miura, Akira Ohta, Ryuta Sekiguchi, Shunji Ito, Shigeki Mori, Tetsuo Okujima Preparation of azulene-substituted benzofurans and isocoumarins was established by the two-types of intramolecular cyclization reaction of 1-ethynylazulenes. 2-(1-Azulenyl)- and 2,3-bis(1-azulenyl)benzofurans were prepared by the palladium-catalyzed cross-coupling reaction of 1-iodoazulenes with...
