Journal ArticleDOI
Converting gem-dimethyl groups into cyclopropanes via Pd-catalyzed sequential C-H activation and radical cyclization.
TL;DR: A novel route to the synthesis of cyclopropane derivatives through Pd-catalyzed sequential C-H activation and radically cyclized to provide 2-(1-alkylcylclopropyl)dimethyloxazolines, which is crucial for the diiodination of the functionalized substrates.
Journal ArticleDOI
Cu(II)-mediated oxidative dimerization of 2-phenylpyridine derivatives
TL;DR: In this article, a variety of 2-phenylpyridine derivatives are oxidatively dimerized at the ortho-position of the phenyl ring in which a net loss of two hydrogen atoms results in the formation of a biaryl compound via a double C-H activation/C-C bond-forming process.
Journal ArticleDOI
Biosynthesis of the Unique Amino Acid Side Chain of Butirosin: Possible Protective-Group Chemistry in an Acyl Carrier Protein-Mediated Pathway
TL;DR: It is reported here that the biosynthesis of AHBA from L-glutamate, encoded within a previously identified butirosin biosynthetic gene cluster, proceeds via intermediates tethered to a specific acyl carrier protein (ACP).
Journal ArticleDOI
Catalytic and stereoselective iodination of prochiral C-H bonds
TL;DR: In this article, Oxazoline-directed cleavage of the β-C-H bonds followed by reaction with I2 gave a wide range of iodinated products, a large range of functional groups are tolerated.
Journal ArticleDOI
Ligand‐Free Copper‐Catalyzed Negishi Coupling of Alkyl‐, Aryl‐, and Alkynylzinc Reagents with Heteroaryl Iodides
TL;DR: An unprecedented ligand-free copper-catalyzed cross-coupling of alkyl-, aryl-, and alkynylzinc reagents with heteroaryl iodides without rearrangement is reported.
