Phenanthroline-t BuONa Promoted Intramolecular C-H Arylation of 1,5-Diaryl-1,2,3-Triazoles for Efficient Synthesis of Triazolophenanthridines

摘要

The first example of phenanthroline- t BuONa promoted intra- molecular C-H arylation of 1,5-diaryl-1,2,3-triazoles without the involvement of transition metals has been developed. Various fused 1,5-disubstituted-1,2,3-triazoles of triazolophe- nanthridines were prepared with excellent yields and high site- selectivity via simple and efficient intramolecular cyclization by using the 1,10-phenanthroline- t BuONa reaction system.
