Efficient access to fluorinated homoallylic alcohols through an indium promoted fluoroallylation reaction
摘要:
Herein, an efficient access to fluorinated homoallylic alcohol is reported. The fluorinated alcohols were obtained in good to excellent yield using indium and halo-fluorinated allylic derivatives. The developed methodology using gamma-substituted halo-fluorinated allylic derivatives gave the corresponding alpha-substituted fluorinated homoallylic alcohol in good yields and good diastereoselectivities up to 86:14.

of α,β-unsaturatedaldehydes to their corresponding (Z)-α-fluoro-α,β-unsaturatedaldehydes has been developed. The first step utilises Selectfluor as a fluorinating agent in CH3NO2/MeOH forming (Z)-α-fluoro-α,β-unsaturatedaldehydes and their corresponding dimethylacetals via methoxyfluorination-elimination. In the second step, water is added to promote the hydrolytic cleavage of the dimethyl acetals
