描述了一种合成新的手性salen型配体的策略，所述配体衍生自α-D-葡萄糖和α-D-甘露糖。通过在糖环的C2和C3位引入适当的官能团得到化合物。配合物在苯乙烯环氧化反应中的效率也进行了研究，并显示出良好的结果，例如，顺式-β-甲基苯乙烯官能化的ee的高达86%。(C)2003爱思唯尔有限公司。保留所有权利。
A strategy for the synthesis of new chiral salen type ligands derived from alpha-D-glucose and alpha-D-mannose is described. The compounds were obtained by introducing appropriate functions at the C2 and C3 positions of the sugar ring. The efficiency of the complexes in the epoxidation of styrenes was also examined and shown to give good results, for example, cis-beta-methylstyrene was functionalised with ee's of up to 86%.
