摘要:研究了几种导致非对映异构的二仲1,4-二醇及其1,4-二磺酸酯消除环化的方法,这些方法导致形成四氢呋喃,并发现它们均通过s N 2型机理进行立体选择,在一个(1,4-二醇)或两个(1,4-二磺酸酯)手性中心构型反转,因此内消旋(即赤型)1,4-二醇和+/-(即苏式)1,4-二甲磺酸酯仅提供反式-2,5-二烷基四氢呋喃,而相应的非对映异构底物仅转化为顺式-2,5-二烷基四氢呋喃.

标题:Synthesis of phosphorus based ligands
发明人：BERENS ULRICH
权利人:CIBA SC HOLDING AG
摘要:Chiral ligands of the formula I or II, may be obtained in high enantiomeric purity from compounds of the formulae III or IV, respectively, with suitable phosphines, where the symbols R₁, R, n, R₃, R₄, R' are as described in claim 1. The products may be converted into transition metal complexes which are useful as catalysts for asymmetric hydrogenation reactions.
