ABSTRACT
Cycloaddition of difluorocarbene to alkenyl boronates 3 gave boron-substituted gem-difluorocyclopropanes 2 in stereospecific fashion. Upon treatment with lithium carbenoids, cyclopropyl boronates 2 underwent one-carbon homologation to afford a variety of gem-difluorocyclopropanes in good yields.
