We succeeded in finding two interesting trends we cannot rule out as having a causal relationship with observed anomeric selectivity that deserve further investigation. The first regards the 2,4-dimethoxy-1,3,5-triazin-2-yl (DMT) glycosides and 2,4-dibenzyloxy-1,3,5-triazin-2-yl (DBT) glycosides. These internal nodes are found early in the tree and are based on reactions from three different publications. Example reactions from each publication are shown in Figure . Our interest was sparked by the variety of conditions and reactants in the α-selective reactions with DMT/DBT donors, starting with Fujimoto's reporting of glycosylations using protected DMT donors under some common glycosylation conditions. High α-selectivity is observed in both reactions in Figure , despite none of the reaction conditions being the same, except the donor and acceptor. It should be noted that the glycosyl donor here is a C-2 deoxy-azido sugar, which, as described earlier, tends to be α-selective. However, they test donors with other, structurally identical leaving groups-such as the corresponding TCA donor-and observe a reduction in stereoselectivity. This indicates that the stereoselectivity cannot be ascribed to the C-2 azido group alone and that the DMT leaving group plays an important role. Ishihara et al. investigated DBT glycosyl donors under very different conditions. In this study, the unprotected DBT-glycosides are reacted with various alcohols under hydrogenolytic conditions, and despite this mode of activation being different from the classic acid activation, high α-selectivity is still observed. This is ascribed to the reaction taking place through an SN2-like mechanism. Tanaka et al. have investigated unprotected DMT-glycosides as donors in metal-catalyzed glycosylations. Both copper, silver, and palladium catalysts show excellent α-selectivity in glycosylations between unprotected DBT-donors and various alcohols. Thus, these three very different methodologies, with the only common denominator being the leaving group, all yield high α-selectivity. This indicates that the DBT/DMT donors might be α-selective of nature and that the scope of α-selective DBT/DMT glycosylations might be broadened to include other substrates and methodologies as well.
