, (2019/02/21)
A simple protocol of iron(III)-catalyzed halogenation of 8-amidoquinolines in water under mild conditions was developed, affording the 5-halogenlated products in good to excellent yields up to 98%. The reaction mechanism most likely involves a single-elec

An efficient and convenient method has been developed to achieve direct silylation of unactivated remote primary or secondary C(sp3)-H bonds to form C-Si bonds with hexamethyldisilane (HMDS). This method highlights the emerging strategy to transform unactivated methyl or methylene into versatile functional groups in organic synthesis and provides a new method to construct functionalized C-Si bonds for synthetic chemistry.

We report a new set of reactions based on the Pd-catalyzed alkylation of methylene C(sp3)-H bonds of aliphatic quinolyl carboxamides with α-haloacetate and methyl iodide and applications in the stereoselective synthesis of various β-alkylated α-amino acids. These reactions represent the first generally applicable method for the catalytic alkylation of unconstrained and unactivated methylene C-H bonds with high synthetic relevance. When applied with simple isotope-enriched reagents, they also provide a convenient and powerful means to site-selectively incorporate isotopes into the carbon scaffolds of amino acid compounds.
