A highly diastereoselective three-step synthesis of 2-O-benzyl-3,4-O-isopropylidene-d-erythrose 9 is described (de >98%; 50% overall yield) starting from d-glyceraldehyde acetonide and (R)-methyl p-tolyl sulfoxide. Treatment of 9 with trifluoroacetic acid gives 2-O-benzyl-d-erythrofuranose.
从d-甘油醛丙酮化物和(R)-开始,描述了2 - O-苄基-3,4 - O-异亚丙基-d-赤藓糖9的高度非对映选择性的三步合成。甲基对甲苯基亚砜。用三氟乙酸处理9得到2 - O-苄基-d-呋喃呋喃糖。
