  Efficient Radical Oxygenation of α-Iodocarboxylic Acid Derivatives

  摘要：

  [GRAPHICS]Treatment of alpha-iodocarboxylic acid derivatives with 2 equiv of triethylborane under oxygen atmosphere gives the corresponding a-hydroxy acid derivatives. This method is based on an iodine atom transfer from the ethyl radical, generated by the reaction of triethylborane and oxygen, with the alpha-iodocarbonyl compound. It offers several advantages over classical ionic substitution reactions: no elimination product is observed, tertiary iodides are efficiently converted to alcohols, and finally, this one-step procedure is working with substrates sensitive to nucleophiles.

  日期：2021.7.16

  The synthesis of symmetrical 3,3′-bisoxindoles from simple acyclic β-oxoanilides is reported. The described method forges three new C–C bonds in a single step via a sequential Mn(OAc)3·2H2O mediated oxidative radical cyclization-fragmentation–dimerization process. The scope of this reaction is demonstrated in the preparation of a variety of 3,3′-bisoxindoles, as well as its application toward the formal

  日期：1998.9

  A new generation of propylene-spaced fluorous allyltin reagents [(Rf(CH2)3)3SnCH2CH = CH2] is described. These succeed in radical allylations where their lower homologs (ethylene-spaced) fail, and they provide improved performance in transition metal catalyzed allylations. The reagents and byproducts are readily separated by simple fluorous-organic liquid-liquid or solid-liquid extractions.

  A fascinating alkene remote migratory isomerization engendered by carbon radical addition to C═C bond in alkenes via bimetallic catalysis has been disclosed. A diverse array of alkenes bearing distantly incorporated the difluoromethylene (RCF2R′) functionality have been expediently obtained. The retainment of C═C bonds in products could serve as an useful synthetic platform furnishing otherwise difficult
