A two-phase bromination process using tetraalkylammonium hydroxide for the practical synthesis of α-bromolactones from lactones

A simple and efficient method for α-brominating lactones that affords α-bromolactones under mild conditions using tetraalkylammonium hydroxide (R(4)N(+)OH(−)) as a base was developed. Lactones are ring-opened with Br(2) and a substoichiometric amount of PBr(3), leading to good yields of the correspo...
