An efficient aminoamidation and aminocyanation reaction of alkenes has been developed for the synthesis of substituted indolines, tetrahydroisoquinolines and pyrrolidines.
Synthesis of highly substituted dibenzoazocine derivatives by the aza-Claisen rearrangement and intramolecular Heck reaction via 8-exo-trig mode of cyclization
The synthesis of highly substituted dibenzo-azocine systems is still lacking. An efficient synthetic protocol utilizing the sequential aromatic aza-Claisen rearrangement followed by the implementation of the intramolecularHeck reaction as a key step has been developed for the synthesis of various dibenzo-azocine derivatives of biological relevance.
A novel approach for copper-promoted intramolecular aminotrifluoromethylation of alkenes using inexpensive CF3SO2Na as the trifluoromethyl source is described. The feature of this method is the concurrent construction of a five-membered ring and a C–CF3 bond in the simple copper salt/TBHP system. A gram-scale reaction was tested with a slight decrease in the yield. This protocol provides an operationally
