The preparation of the novel iodo glucal 5 from 3,4,6-tri-O-(triisopropylsilyl)-D-glucal (4), via a two-step procedure involving C1 stannylation and subsequent tiniodine exchange, is described. The palladium-catalyzed coupling of 5 with a variety of metalated aromatics provides a facile and high yielding entry into C-aryl glucals, compounds that have been demonstrated to be useful precursors for the synthesis of C-aryl glycosides.
