Electrooxidative C-H Functionalization of Heteroarenes. Thiocyanation of Pyrazolo[1,5-a]pyrimidines

Efficient electrooxidative C-H thiocyanation of both high and low reactive pyrazolo[1,5-a]pyrimidines using a new system of complementary approaches has been developed. Advantages of this promising strategy are the undivided cell, mild conditions, and readily available reagents as well as feasible scaling up process and transformation of the synthesized aryl thiocyanates to new thiols. Also, target thiocyanates were found to have pronounced antifungal activity.
