We reported the synthesis of tetrasubstituted alpha-fluoroenones from tetrasubstituted gem-bromo-fluoroolefins in good yields. These compounds are scarcely studied in the literature, due to difficulty of synthesis, whereas they could serve as intermediates in the synthesis of biological relevant molecules and could also be envisioned to design new constrained peptidomimetics.

A Facile and Mild Method for the Synthesis of Terminal Bromofluoroolefins via Diethylzinc-Promoted Wittig Reaction
摘要:
Synthesis of 1-bromo-1-fluoroolefins was achieved in good yields via a Wittig reaction promoted by diethylzinc, even with nonactivated aldehydes and ketones as starting materials.

An unprecedented cross-coupling reaction of alkyl carbagermatranes with bromofluoroolefins to deliver dialkyl-substituted monofluoroalkenes was achieved. This cross-coupling reaction was performed under base/additive-free conditions with excellent functional group tolerance, therefore offering an opportunity for challenging dialkyl-substituted monofluoroalkenes. The preparation of bioactive agent analogues
