  Benzotriazole-mediated 4-position derivatization of 2,6-diarylpyrylium cations by electrophiles

  摘要：

  2,6-Diaryl-4H-(benzotriazolyl)pyrans (7a-c) on treatment with n-butyllithium undergo smooth lithiation at the position a: to the benzotriazolyl moiety. In contrast to fused and bridged pyranyl derivatives, these pyranyl anions react with electrophiles by two routes: i) the expected electrophilic substitution resulting in various 4-alkyl- and 4-(omega-alkylfunctionalized)-pyrylium salts (12-19) or iii pyrylium ring rearrangement of 2,6-diarylpyrylium anions (8a-c), leading to 1,2-diaryl-3,1-cyclopentadien-1-ols (10a-c).

  2,6-diphenylpyrylium and 2,6-di-t-butylpyrylium perchlorates are easily converted into a number of the corresponding 4-alkyl derivatives by photochemical reaction with tetraalkylstannanes, in MeCN at room temperature. The mechanism of the process is discussed.
