our search for a new class of HMG-CoA reductase inhibitors, the synthesis of reaction intermediate analogues was investigated. Compound 2, having the C-5 (R) configuration of natural mevinic acids, was prepared in enantiomerically pure form starting from levoglucosan. During this synthesis, an epimerisation of the olefinic intermediate 16 was observed and was found to depend strongly both on the axial
在我们寻找一类新的HMG-CoA还原酶抑制剂的过程中,研究了反应中间体类似物的合成。以左旋葡聚糖为原料,以对映体纯的形式制备具有天然甲胎酸的C-5(R)构型的化合物2。在该合成过程中,观察到烯烃中间体16的差向异构化,并且发现它强烈依赖于轴向或赤道取向以及C-3取代基的性质。报道了化合物2的生物活性。
