A straightforward regio- and diastereoselective process has been developed for the synthesis of unprecedented symmetrical trans-α,α′-bis(diphenylphosphoryl)- and α,α′-bis(diphenylphosphorothioyl)-cycloalkanones, through the reaction of cyclic enamines with excess P-chlorodiphenylphosphine in the presence of triethylamine, followed by oxidation or sulfurization and hydrolytic workup.
通过环状烯胺与过量的 P 反应,开发了一种直接的区域选择性和非对映选择性方法,用于合成前所未有的对称反式-α,α'-双(二苯基磷酰基)-和 α,α'-双(二苯基磷硫酰基)-环烷酮-氯二苯基膦在三乙胺存在下,然后氧化或硫化和水解处理。
