  Converting gem-Dimethyl Groups into Cyclopropanes via Pd-Catalyzed Sequential C−H Activation and Radical Cyclization

  摘要：

  A novel route to the synthesis of cyclopropane derivatives is described. 1,1-Dimethyls in 2-(1,1-dimethylalkyl)dimethyloxazolines are first converted into 1,3-diiodide derivatives via Pd-catalyzed sequential C-H activation and then radically cyclized to provide 2-(1-alkylcylclopropyl)dimethyloxazolines. The use of EtOAc as a solvent is crucial for the diiodination of the functionalized substrates.

  Palladium-Catalyzed β-Mesylation of Simple Amide via Primary sp³ C–H Activation

  摘要：

  A beta-mesylation of primary sp(3) C-H bonds from simple amides with methanesulfonic anhydride; (Ms2O) has been established successfully A 80 degrees C in a Pd(OAc)(2) (catalyst)/K2S2O8 (oxidant)CF3CH2OH (solvent) system. These amide substrates involve N-monosubstituted linear,, branch, or cyclic alkanes, and electron-deficient benzyl compounds. The beta-mesylated amide products can be converted easily to beta-fluoroamideS or beta-lactams through inter- or intramolecular S(N)2 processes.

  by Pd-catalyzed C(sp3)–H bond functionalization was developed. Using a bidentate directing group, the direct and selective introduction of a SCF3 moiety was possible on a range of amides with remarkable selectivity for C(sp3)-centers with an electrophilic SCF3 source and pivalic acid as an additive. This work constitutes an example of the unactivated C(sp3)–SCF3 bond formation by C–H activation offering

  Disclosed herein is a copper(II)-mediated chelation-assisted intermolecular amination of inert C(sp3)H bonds using simple alkylamines as the amino source. A straightforward and step-economic alternative to α,α-disubstituted β-amino acid derivatives is provided consequently. This reaction features good functional group tolerance and relatively broad substrate scope. Furthermore, a coupling product between

  copper‐catalyzed alkynylation/annulation of aliphatic amides with alkynyl carboxylic acids is discussed in this paper. A broad range of easily accessible alkynyl carboxylic acids were introduced at the β‐methyl group of aliphatic amides with the assistance of an 8‐aminoquinolyl auxiliary group via decarboxylation to achieve the subsequent cyclic CN bond formation within one hour.
