supporting information, p. 966 - 970 (2018/02/23)
Diels-Alder reaction of 1,3-diarylbenzo[c]furan/cyclopentadienone with TTF followed by triflic acid mediated cleavage of the resulting adducts led to the formation of the respective 1,4-diaryl substituted naphthalenes, fluoranthenes, and fluorenones. The photophysical properties of representative diaryl-substituted hydrocarbons are also reported.
Synthesis of fluorene- and spirobifluorene-fused thiophenes
Yao, Wen,Liu, Qiancai,Shi, Yingbo,Tang, Jie
experimental part, p. 1077 - 1088 (2012/07/28)
A novel synthetic route to fluorene- and spirobifluorene-fused thiophenes is explored by starting with ninhydrin. The Diels-Alder cycloaddition was employed to construct the key intermediate, 2,3-bis(hydroxymethyl)-1,4-diphenyl- fluorenone, which was furt
Addition of Phthalimidonitrene to Tetrasubstituted Cyclopentadienones
Narasimhan, K.,Rajakumar, P.
, p. 141 - 143 (2007/10/02)
The aziridines (3, 7, 10) obtained by the cycloaddition of phthalimidonitrene (1) to indanocyclone (2), phencyclone (6) and acecylone (9) undergo cycloreversion when treated with hydrazine hydrate, through the intermediacy of N-aminoaziridines.Aziridine (3) when treated with p-TsOH gives (5).Thermolysis of the aziridines (3) and (10) furnishes the rearranged products.
