A highly diastereoselective and straightforward synthesis for (Z)-2-fluoroallylic alcohols via a Nozaki−Hiyama−Kishi-type reaction with the corresponding bromofluoroolefins was developed, providing an easy access to highly interesting fluorinated synthons.
Highly Stereoselective Synthesis of Fluoroalkene Dipeptides via the Novel Chromium(II)-Mediated Carbon–Fluorine Bond Cleavage/New Carbon–Carbon Bond Formation
the novel reductivecoupling, four types of fluoroalkene dipeptide analogues could be stereoselectively prepared. An efficient chromium(II)-mediated reductivecoupling reaction of various CBrF2-containing molecules and aldehydes has been developed. This reaction proceeds presumably via the monofluorinated dichromium(III) intermediate generated by the carbon–fluorine bond activation, and provides a
