WebNov 24, 2024 · Abstract. 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 … WebThis generates α-phosphonyloxy enolates that are subsequently intercepted by aldehydes, leading to [1,4] O→O dialkoxyphosphinyl migration and finally to intramolecular ring closure. This protocol was used to synthesize a range of enantioenriched trans -α,β-epoxy imidates in moderate to high yields with excellent diastereoselectivities.
