An array of C-aryl and C-vinyl furanosides were prepared in good yields and diastereoselectivities from C-halogeno furanosides either with aryl Grignard or with vinyl Grignard using the convenient Co­(acac)3/TMEDA catalytic system. This method is illustrated by the total synthesis of the (−)-isoaltholactone.
