An efficient methodology has been developed for the one-pot or telescoped synthesis of aliphatic sulfonamides, sulfonyl fluorides, and unsymmetrical sulfones on the basis of interrupted alkylation of sodium hydroxymethylsulfinate (rongalite) with alkyl halides. The protocols are conducted under mild conditions, use inexpensive and shelf-stable reagents, and are not sensitive to air/moisture. These
已经开发了一种有效的方法,用于在羟甲基亚磺酸钠(荣格石)与烷基卤的间断烷基化的基础上,单锅或望远镜式合成脂族磺酰胺,磺酰氟和不对称砜。该方案是在温和的条件下进行的,使用廉价且耐贮存的试剂,并且对空气/水分不敏感。这些条件可用于快速平行化学合成,这是通过基于抗凝血药替罗非班的核心结构制备小的磺酰胺库证明的。
