A novel method is reported for preparing methyl 6-deoxy-3-O-methyl-alpha-L-mannopyranoside (1) by asymmetric synthesis, using 2-acetylfuran (2), a non-chiral simple molecule, as the starting material and achieving high yields via (S)-1-(2-furyl)ethanol and (S)-1-(2,5-dihydro-2,5-dimethoxy-2-furyl)ethanol.
报道了一种新方法,该方法以非手性简单分子2-乙酰基呋喃(2)为起始原料,通过不对称合成制备甲基6-脱氧-3-O-甲基-α-L-甘露聚糖。通过(S)-1-(2-呋喃基)乙醇和(S)-1-(2,5-二氢-2,5-二甲氧基-2-呋喃基)乙醇获得高收率。
