Construction of new fluorophores by Diels-Alder reaction of diacenaphthothiophenes
Yamamoto, Yuma Fukuoka, Yoshiaki Nishida, Jun-ichi Kitamura, Chitoshi Kawase, Takeshi
The Diels–Alder (DA) reaction of diacenaphtheno[1,2-b;1′,2′-d]thiophene (1a) with benzyne affords 1:1 and 1:2 adducts, 7 and 8, in 47 and 11% yields. An X-ray crystallographic analysis reveals that 8 possesses a dibenzobarrelene structure involving a rigi
THE ADDITION OF BENZYNE TO AZULENE
Cresp, Terry M. Wege, Dieter
The title reaction afforded the Diels-Alder adduct 4b,10-etheno-benzazulene (4), while an analogous reacton involving 5,6-dichloroazulene gave the 6,7- and 7,8-dichloro-derivatives of (4).Treatment of (4) with 3,6-di(pyridin-2-yl)-s-tetrazine yielded b
