A number of carbocyclic analogues of the fructose-derived ketone 1 have been prepared and investigated for asymmetric epoxidation. The studies show that the oxygen atom of the pyranose ring of 1 has an impact on the catalyst's activity and selectivity. Conformational, electronic, and steric effects are discussed.
已经制备了果糖衍生的酮1的许多碳环类似物,并进行了不对称环氧化的研究。研究表明,吡喃糖环1的氧原子对催化剂的活性和选择性有影响。讨论了构象效应,电子效应和空间效应。
