Oxa- and Azacycle-Formation via Migrative Cyclization of Sulfonylalkynol and Sulfonylalkynamide,ompanied 1,2-migration of the sulfonyl groups. This reaction provides a novel access to oxa- and azacycles possessing a pendant vinyl sulfone functionality, which in turn is amenable to further transformations. During research on this migrative cyclization, mechanism studies indicated that nucleophi作者: Repetitions 時間: 2025-3-22 04:28 作者: 圖畫文字 時間: 2025-3-22 04:34 作者: Initial 時間: 2025-3-22 10:03

Further investigations showed that a catalytic amount of phosphine or 4-(.-dimethylamino)pyridine (DMAP) also promoted migrative cyclization in an a. Umpolung manner similarly. Furthermore, asymmetric induction was observed when a chiral DMAP derivative was used in the reaction.作者: 獨(dú)裁政府 時間: 2025-3-23 08:21 作者: 善于 時間: 2025-3-23 13:18 作者: Enthralling 時間: 2025-3-23 15:31

The possibility of enantiocontrol of this reaction was indicated by the use of chiral phosphine and binaphthyl-based chiral DMAP. Further investigation on developing an efficient enantioselective variant is currently in progress in this laboratory.作者: 水獺 時間: 2025-3-24 00:00
