Transition Metal-catalyzed cyclization reaction of enediynes to benzo[b]naphtho[2,1-d]thiophene

Chen, Chiu-Mei 28 June 2012 (has links)
Treatment of thioanisole-substituted aryldiyne with 2 equiv. of N-Iodosuccinimide and 5 mol% of PPh3AuCl and 5 mol% AgSbF6 in refluxing dichloromethane gave 5-iodo benzo[b]naphtho[2,1-d]thiophene in good yields. This method tolerated various functional groups in alkyl and phenyl moiety. We also treatment thioanisole-substituted aryldiyne with 10 mo% of PdX2 and 3 equiv. CuX2 (X= Cl, Br),in reluxing THF gave in 5-position have halogen substitute benzo[b]naphtho[2,1-d]thiophene derivative.
