of novel, aryl and aralkyl D-mannopyranosides and 1-thio-D-mannopyranosides were synthesized for evaluation of insulin-like and insulin-antagonistic properties. The substituted-phenyl alpha-D-mannopyranosides were prepared by the general procedure of Helferich and Schmitz-Hillebrecht, the substituted-phenyl 1-thio-alpha-D-mannopyranosides by a method corresponding to the Michael synthesis of aromatic
合成了许多新颖的芳基和芳烷基D-甘露糖吡喃糖苷和1-硫代-D-甘露糖吡喃糖苷,用于评估胰岛素样和胰岛素拮抗性质。通过Helferich和Schmitz-Hillebrecht的通用方法制备取代的苯基α-D-甘露糖吡喃糖苷,通过对应于芳族糖苷的迈克尔合成的方法制备取代的苯基1-硫代α-D-甘露糖吡喃糖苷,以及芳烷基。通过2,3,4,6-四-O-乙酰基-1-硫代-α-D-甘露吡喃糖的芳烷基化作用制备1-硫代-α-D-甘露吡喃糖苷(15),然后进行O-脱乙酰化。通过将2-O-乙酰基-α-D反应的产物2-S-(四-O-乙酰基-α-D-甘露吡喃糖基)-2-thiopseudourea氢溴酸盐中的mid基进行碱性裂解,得到化合物15。 -甘露糖基溴与硫脲。苄基1-硫代-β-D-甘露吡喃糖苷
