, p. 6006 - 6009 (2016/01/09)
An efficient domino process for the synthesis of thioflavanones has been described using a copper catalyst without addition of any external ligand. A variety of thioflavanones have been synthesized from easily accessible 2′-iodochalcones or 2′-bromochalco
Cycloaddition of Benzothiete to 4-Substituted Styrenes
Meier, Herbert,Schmidt, Michael,Eckes, Heinz-Ludwig
, p. 1545 - 1550 (2007/10/02)
By thermal ring opening benzothiete (1) generates an 8-? electron system 2, which forms the cycloadducts 4/5a-j with 4-substituted styrenes 3a-j.The enhancement of the reactivity by electron-donating as well as electron-withdrawing substituents and their influence on the regioselectivity are discussed by applying frontier orbital calculations. - Key Words: Cycloaddition; Substituent effects; Reactivity; Regioselectivity; FMO calculations

Nakazumi, Hiroyuki,Ueyama, Tamio,Endo, Takashi,Kitao, Teijiro
, p. 1251 - 1252 (2007/10/02)
2-Phenylbenzothiopyrylium perchlorates were conveniently prepared in good yields by reduction of 2-phenyl-4H-benzothiopyran-4-ones (thioflavones) with aluminium hydride, followed by treatment with acid in the presence of 2,3-dichloro-5,6-dicyano-p-b
