A green synthetic method to construct heterocyclic compounds containing pyrazole core and tertiary alcohol ester moiety is reported, with inexpensive and easily accessible FeCl3 serving as catalyst. This method features a broad substrate scope, high functional group tolerance, and operational simplicity with yields ranging from 82% to 98%. Furthermore, the practicality of this protocol is highlighted by scale-up experiments and synthetic transformations of the products, including the modification of marketed drugs.
