  未活化烯烃和炔烃的自由基氢氟磺酰化

  摘要：

  通过使用FABI作为FSO 2 -自由基前体和ODA作为有机光催化剂，已经成功地实现了烯烃的自由基氢氟磺酰化。使用这种光催化系统，炔烃的自由基氢氟磺酰化也可以以独特的高Z选择性实现。在天然产物的后期修饰和药物连接化学中进一步证明了该方法的利用。

  Asymmetric cycloetherification based on a chiral auxiliary for 4-acyloxy-1-butene substrates during oxidation with iodosylbenzene via a 1,3-dioxan-2-yl cation

  摘要：

  Reaction of but-3-enyl camphanate and its derivatives with iodosylbenzene yielded tetrahydrofuran-3-yl camphanate with high diastereomeric ratio via a 1,3-dioxan-2-yl cation intermediate. The reaction using (IS)-camphanate as a chiral auxiliary preferentially gave (S)-3-acyloxytetrahydrofuran and (2S,3S)-3-acyloxy-2-silyltetrahydrofuran. (C) 2009 Elsevier Ltd. All rights reserved.

  Radical hydro-fluorosulfonylation of olefins has been successfully achieved by employing FABI as a FSO2-radical precursor and ODA as an organic photocatalyst. With this photocatalytic system, radical hydro-fluorosulfonylation of alkynes can also be realized with a unique, high Z-selectivity. Utilization of this method is further demonstrated in the late-stage modification of natural products and drug
