  BF₃·Et₂O-Promoted Cleavage of the C_sp–C_sp2 Bond of 2-Propynolphenols/Anilines: Route to C2-Alkenylated Benzoxazoles and Benzimidazoles

  摘要：

  A novel BF3 center dot Et2O-promoted tandem reaction of easily prepared 2-propynolphenols/anilines and trimethylsilyl azide is developed to give C2-alkenylated benzoxazoles and benzimidazoles in moderate to good yields. Most reactions could be accomplished in 30 min at room temperature. This tandem process involves a C-sp-C-sp2 bond cleavage and a C-N bond formation. Moreover, both tertiary and secondary propargylic alcohols with diverse functional groups were tolerated under the mild conditions.

  method of 2‐styrylbenzoxazoles by oxidative intramolecular cyclization of styrylphenolic Schiff bases with thianthrene cation (Th+.ClO4−) is described. The oxidative cyclization of Schiff bases in the presence of 2,6‐di‐tert‐butyl‐4‐methylpyridine (DTBMP) gives 2‐styrylbenzoxazole derivatives in better yields than those in the absence of DTBMP.

  通过与噻蒽阳离子styrylphenolic席夫碱氧化分子内环化（TH的2-苯乙烯苯并恶唑甲简单而快速的方法制备。+ CLO 4 - ）进行说明。在没有2,6-二叔丁基-4-甲基吡啶（DTBMP）的情况下，席夫碱的氧化环化产生的2-苯乙烯基苯并恶唑衍生物的收率要高于不存在DTBMP的情况。
