The fragmentation of primaryalkoxylradicals has been scarcely used in synthesis since other competing processes (such as oxidation or hydrogen abstraction) usually predominate. However, when serine derivatives were used as substrates, the scission took place in excellent yields. Tandem scission−allylation, −alkylation, or −arylation reactions were subsequently developed. This one-pot methodology
