Efficient Synthesis of Isoquinoline Derivatives via AgOTf/Cu(OTf)2-Cocatalyzed Cyclization of 2-Alkynyl Benzaldoxime
摘要:
An efficient, AgOTf and Cu(OTf)(2) multicatalytic intramolecular cycloisomerization of 2-alkynylbenzaldoxime is reported. Isoquinoline N-oxides have been found to be deoxygenated to the corresponding quinolines in good yields in dimethylformamide/dichloroethane (v/v 5:1) as solvent at 120 degrees C.
