Abstract

In this work, the multi-step synthesis of three novel pyrimidopteridine photoredox catalysts is reported. These catalysts contain di(carboxyalkyl)-substitution at the 3- and 7-positions as handles for further synthetic modifications. The catalysts are fully characterized including by photochemical and electrochemical means. Additionally, a catalytic application in the oxidative annulation of 2-phenylbenzoic acid is presented.
