Application of the superarmed glycosyl donor to chemoselective oligosaccharide synthesis

Recently, we discovered a novel method for "superarming" glycosyl donors. Herein, this concept has been exemplified in one-pot oligosaccharide syntheses, whereby the superarmed glycosyl donor was chemoselectively activated over traditional "armed" and disarmed glycosyl acceptors. Direct side-by-side comparison of the reactivities of the classic armed and superarmed glycosyl donors further validates the credibility of the novel concept.
