报道了利用2-O-三氟乙酞基-3,4,6-三-O-苄基-α-D-吡喃甘露糖基三氯乙酸酯在Lewis酸催化下通过分子内亲核取代反应立体选择性合成β-D-吡喃甘露糖苷的新方法,并讨论了该方法可能的机理.
Reported the use of 2-O-trifluoroacetyl-3,4,6-tri-O-benzyl-α-D-mannopyranosyl trichloroacetate in Lewis acid catalyzed by an intramolecular nucleophile The new method of stereospecific synthesis of β-D-mannopyranoside was discussed, and the possible mechanism of this method was discussed.
