[reaction: see text] The electrooxidative glycosylation of newly designed 1-arylthio-substituted 2,3-dideoxyglycosides is described. The halide salt-mediated electrooxidation utilizing either of the alpha- or beta-thiodideoxyglycosides proceeded smoothly at -78 degrees C to give dideoxynucleosides in a beta-selective manner, presumably through a 1-halo-substituted glycosyl donor.

硫代二氧苷的任何一种,在卤化物盐介导的电氧化作用下,在-78℃下以β-选择性的方式平稳地产生双脱氧核苷,大概是通过1-卤代的糖基供体。
