日期:——
reductive coupling of dienol ethers with N-tosylimines catalyzed by Ni(0) in the presence of a VAPOL-derived phosphoramidite ligand follows an unprecedented regiochemicalcourse; it furnishes syn-configured 1,2-aminoalcohol derivatives in good chemical yields with up to 94% ee.
在 VAPOL 衍生的亚磷酰胺配体存在下,二烯醇醚与N-甲苯磺酰亚胺在 Ni(0) 催化下发生还原偶联,遵循前所未有的区域化学过程;它以良好的化学收率提供顺式构型的 1,2-氨基醇衍生物,其 ee 高达 94%。
