AgSCF3/Na2S2O8-Promoted Trifluoromethylthiolation/Cyclization of o-Propargyl Arylazides/o-Alkynyl Benzylazides: Synthesis of SCF3-Substituted Quinolines and Isoquinolines
摘要:
A AgSCF3/Na2S2O8-promoted trifluoromethylthiolation/cascade cyclization of o-propargyl arylazides (or o-alkynyl benzylazides) triggered by a carbon carbon triple bond is reported. This strategy provides the synthesis of " valuable SCF3-substituted quinoline and isoquinoline systems via the construction of one C(sp(2)) SCF3 bond and one C-N bond within one process.

A strategy for the synthesis of isoquinolylselenocyanates and quinolylselenocyanates through electrophilicselenocyanogencyclization has been developed. The feature of this reaction is that the sequential process was induced directly by generated in situpseudohalogen (SeCN)2generated in situ. Additionally, the obtained selenocyanates allowed functional group diversification, which could be potential
