A novel enantioselective preparation of α-fluoro-β-keto acids
摘要:
A two-step method for the enantioselective preparation of alpha-fluorinated beta-keto acids from 1,3-dioxin-4-ones having l-menthone as the chiral auxiliary at the 2-position is described. The method consists of fluorination of the dioxinones by molecular fluorine and solvolytic cleavage of the acetal function.
