Zhang, Zhong published the artcileVisible-Light-Promoted Oxy-Difluoroalkylation Of Aryl Alkynes For The Synthesis Of β-Fluoroenones And α-Difluoroalkyl Ketones, Synthetic Route of 401-55-8, the publication is Advanced Synthesis & Catalysis (2021), 363(13), 3348-3353, database is CAplus.
A method for regio-, stereoselective synthesis of (E)-β-fluoroenones I [R = H, Et, nPr; R1 = CO2Et, C(O)NEt2, P(O)(OEt)2, pyrrolidin-1-yl; Ar = Ph, 4-MeC6H4, 4-BrC6H4, etc.] was synthesized via visible light irradiated oxy-difluoroalkylation of alkynes using di-fluoroacetates and water as oxygen source, potassium carbonate as base. Also, α-difluoroalkyl ketones II [Ar1 = Ph, 2-thienyl, 4-ClC6H4, etc.; R2 = Me, Et, nPr, etc.] were obtained using phenylpyridine as base under same reaction conditions. These transformations featured mild condition, wide functional tolerance and step economy. The large-scale transformations and further derivatization showed its potential application in organic synthesis.
