A new route to intermediates for the synthesis of 2′-deoxy-4′-thionucleosides is described. By utilising enantiomeric erythro-dibenzyldithioacetals, both D- and L-3-O-(N-acyl)carbamoyl thiosugars, which give β-selective glycosylations, are radily produced.
描述了合成2'-脱氧-4'-硫代核苷的中间体的新途径。通过利用对映异构的赤型-二苄基二硫缩醛,放射状地产生D-和L-3- O-(N-酰基)氨基甲酰基硫糖基,它们产生β-选择性的糖基化。
