Auxiliary-Enabled Pd-Catalyzed Direct Arylation of Methylene C(sp<sup>3</sup>)–H Bond of Cyclopropanes: Highly Diastereoselective Assembling of Di- and Trisubstituted Cyclopropanecarboxamides
An auxiliary-enabled and Pd(OAc)2-catalyzed directarylation of C(sp(3))-H bonds of cyclopropanes and production of di- and trisubstitutedcyclopropanecarboxamides having contiguous stereocenters are reported. The installation of aryl groups on cyclopropanecarboxamides led to the assembling of novel mono- and di- aryl-N-(quinolin-8-yl)cyclopropanecarboxamide scaffolds and mono- and di- aryl-N-(2-(
Correction to Auxiliary-Enabled Pd-Catalyzed Direct Arylation of Methylene C(sp<sup>3</sup>)–H Bond of Cyclopropanes: Highly Diastereoselective Assembling of Di- and Trisubstituted Cyclopropanecarboxamides
In Scheme 6, for the preparation of 5d from 4a, the reaction condition “1a (0.25 mmol)” has to be omitted. See the corrected Scheme 6. We realized that in the protonNMRspectral data of various compounds given in the Supporting Information corrections in the coupling constants and multiplicity assignment are required. The protonNMR processing software was inadvertently set to use fewer numbers of
Diastereoselective Pd(II)-Catalyzed sp<sup>3</sup>C–H Arylation Followed by Ring Opening of Cyclopropanecarboxamides: Construction of<i>anti</i>β-Acyloxy Carboxamide Derivatives
diastereoselective Pd(OAc)2-catalyzed, bidentate ligand-directed sp3 C–H activation/arylation followed by ring opening of cyclopropanecarboxamides, which were assembled from cyclopropanecarbonyl chlorides and bidentate ligands (e.g., 8-aminoquinoline and 2-(methylthio)aniline), has been investigated. The treatment of various cyclopropanecarboxamides with excess amounts of aryl iodides in the presence of the Pd(OAc)2
