  摘要：

  AbstractOptically active β‐hydroxy sulfonamides and β‐hydroxy sulfones are very important building blocks for the preparation of bioactive compounds and pharmaceuticals. In this work, a highly efficient asymmetric hydrogenation of β‐keto sulfonamides and β‐keto sulfones has been developed using the phosphine‐free chiral ruthenium complex Ru(OTf)(TsDPEN)(η6‐p‐cymene) as the catalyst, to afford the corresponding β‐hydroxy sulfonamides and β‐hydroxy sulfones in high yields with excellent optical purities. In addition, a cascade asymmetric hydrogenation/dynamic kinetic resolution (DKR) of racemic cyclic β‐keto sulfonamides and β‐keto sulfones was also realized using the same catalyst, to give the corresponding chiral cyclic β‐hydroxy sulfonamides and β‐hydroxy sulfones in good yields with excellent enantio‐ and diastereoselectivities.magnified image

  摘要：

  二氧化硫与环氧硅烷或烯丙基硅烷的烯反应生成甲硅烷基亚磺酸盐，可将其溴化（Br 2或NBS）或氯化（NCS或Cl 2）以生产相应的磺酰卤。它们与伯胺和仲胺或醇反应，分别得到相应的磺酰胺和磺酸酯。将二氧化硫异狄尔斯-阿尔德加成到1-氧基或1,3-二氧基-1,3-二烯上会生成两性离子，该两性离子会加到环氧硅烷或烯丙基硅烷中，生成甲硅烷基亚磺酸盐，可将其原位转化为多官能磺酰胺或磺酸酯。这样可以通过一锅，三和四组分方法快速访问复杂的磺酰胺和磺酸酯库。

  A series of N-alkyl-2-oxoalkanesulfonamides have been synthesized by reacting silyl enol ethers with N-alkyl-sulfamoyl chlorides. Their reactivity towards electrophiles was investigated in order to explore the regio-and stereoselectivity of the process. 2-Oxoalkanesulfonamides were used to prepare 5-(methylsulfamoyl)-1,4-dihydropyridines derivatives.
