Electrophilic substitution reactions of trisheteroarylinethanes: an efficient strategy to develop novel synthons for organic synthesis

摘要

Trisheteroarylmethanes are interesting molecules for the construction of three dimensionally complex systems. From this vantage point, we studied electrophilic substitution reactions on tris-2-thienylmethane and tris-2-furylmethane. During the bromination reaction, we have isolated the tris-bromosubstituted tris-2-thienylmethane in the former case and brominated furanones in the latter case, which may be of synthetic and biological importance.
