Ring opening of 3-oxo-1,2-cyclopropanated sugars with thiols leads to the serendipitous discovery of the synthesis of sugar based homologated acyclic dithioacetals. These acyclic dithioacetals were found to undergo one-pot septanoside formation followed by stereoselective glycosylation in the presence of glycosyl acceptors under glycosylation reaction conditions.
3-氧代-1,2-环丙烷化的糖与硫醇的开环导致偶然发现了基于糖的同源无环二硫缩醛的合成。发现这些无环二硫缩醛在糖基化反应条件下,在存在糖基受体的情况下经历一锅的七糖苷的形成,然后进行立体选择性糖基化。
