A novel, mild, metal-free procedure for the C-H acetalization of O-heterocycles via visible light activation using phenylglyoxylic acid as the photoinitiator is presented. Biomass-derived O-heterocycles such as THF can be used, and a variety of alcohols with different functionalities can be successfully employed to afford the desired acetals in high yields. Convenient acidic deprotection was also carried out.

Biomass-derived O-heterocycles, like THF, can be employed, while primary, secondary alcohols and alcohols bearing a variety of functionalities were succesfully employed, affording the desired acetals in high yields. Facile acidic deprotection was also performed.
