首次将氢甲酰化反应应用于异山梨醇酯和异甘油醚的烯烃衍生物,形成了新的碳-碳键。根据配体和反应条件的不同,C6异构体a以4:1的比例合成,产率较高;而C5异构体b的区域选择性几乎完全(46:1),产率较高。在大多数情况下,只观察到所得到的醛的外取向,并且该方法也很容易在1g尺度上应用。
The first time application of hydroformylation on olefinic derivatives of isosorbide and isomannide is shown by which a new carbon-carbon bond is formed. Depending on the ligand and reaction conditions used, the C6 regioisomer a can be obtained in 4:1 ratio and excellent yield, whereas C5 isomer b is achieved in almost complete regioselectivity (46:1) and good yield. In the majority of cases only the exo orientation is observed for the obtained aldehydes, and the method is easily applicable also on a 1 g scale.
