A regio- and chemoselective sulfonylation of propargyl alcohols with sulfinamides in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) was developed. It provided straightforward and mild access to multi-substituted allenyl sulfones by using sulfinamides as the sulfonyl sources. This transformation was promoted by HFIP and did not require any catalysts or oxidants, which allowed for the successful conversion
开发了 1,1,1,3,3,3-六氟异丙醇 (HFIP) 中炔丙醇与亚磺酰胺的区域和化学选择性磺酰化反应。它通过使用亚磺酰胺作为磺酰源,提供了直接和温和地获得多取代的联烯基砜的途径。这种转化是由 HFIP 促进的,不需要任何催化剂或氧化剂,这使得各种叔和仲炔丙醇能够以高产率成功转化为丙二烯砜。
