WebNov 24, 2024 · A simple, room temperature approach for the fast single‐step synthesis of α‐phosphonyloxy ketone, a drug scaffold, has been developed which involves highly reactive species i.e., 1,2‐dicarbonyls that readily react with trialkyl phosphites and formic acids in batch as well as in continuous‐flow with the flow rate of 3 ml/min ( tR = ∼4 s). WebCoupling of α-ketoesters with imines initiated by diethyl phosphite in the presence of alkaline metal hexamethyldisilazides is reported. Base-promoted addition of diethyl phosphite to α-ketoesters, followed by [1,2]-phosphonate/phosphate rearrangement, generates α-phosphonyloxy enolates that are subsequently intercepted by imines.
