Multicatalytic tandem reaction of N'-(2-alkynylbenzylidene)hydrazide with indole.
The combination of AgOTf and Dy(OTf)(3) shows high efficiency as a catalyst in the tandem reactions of N'-(2-alkynylbenzylidene)hydrazides with indoles, which generate the unexpected 1-(indol-3-yl)-2-aminoisoquinolinium triflates in good yields.
