A catalyst-free novel and efficient methodology for the challenging synthesis of benzo-oxetes from 2'-hydroxyacetophenones mediated by sulfuryl fluoride (SO2F2) gas has been realized. The combination of 2'-hydroxyacetophenones and SO2F2 furnishes synthetically challenging benzo-oxetanes in moderate to excellent yields. The highlight of this work is the design and synthesis of strained four-membered oxete rings.
一种无催化剂的新颖高效方法已实现,用亚砜氟化物(SO2F2)气体介导从2'-羟基苯乙酮合成苯并噁唑。2'-羟基苯乙酮和SO2F2的组合以中等至优良的产率合成了合成上具有挑战性的苯并噁唑。这项工作的亮点是设计和合成了紧张的四元氧噁唑环。
