Transition metal-free approach for late-stage benzylic C(sp)-H etherifications and esterifications

We report a transition metal-free approach for the regioselective functionalization of benzylic C(sp 3 )-H bonds using alcohols and carboxylic acids as the nucleophiles. This straightforward and general route has provided various benzylic ethers and esters, including twelve pharmaceutically relevant compounds. Herein, we report a transition metal-free approach for the regioselective functionalisation of benzylic C(sp 3 )-H bonds using alcohols and carboxylic acids as the nucleophiles. Late stage functionalization has been done with complex drug molecules.
