Synthesis of 2,5-disubstituted 6-azaindoles from substituted aziridines via intramolecular cyclization.
A new and efficient preparation of pharmacologically and biologically important 2,5-disubstituted 6-azaindoles was achieved from cyclizations of aziridin-2-yl dipropargylic alcohols as adducts of two
A Flexible Convergent Route to Azaoxindoles, Azaindolines, Azaindoles, and Tetrahydroazaquinolones
A variety of azaoxindoles, azaindolines, azaindoles, and tetrahydroazaquinolones can be readily prepared by cyclisation onto pyridine rings of radicals derived from xanthates. The xanthate precursors
The ortho and meta magnesiation of functionalized anilines and amino-substituted pyridines and pyrazines at room temperature.
These magnesiations are compatible with several carbonyl functionalities and allow access to polysubstituted anilides in satisfactory yields.
Synthesis and Characterization of Unsymmetric 4-Picolyl Selenides
GRAPHICAL ABSTRACT Abstract A number of unsymmetrical heteroaryl 4-picolyl selenides have been prepared by lithiation of 4-picoline using lithium diisopropylamide under cryogenic conditions. The
Organometallic methods for the synthesis and functionalization of azaindoles.
In this tutorial review, a survey of the recent development of organometallic chemistry-based methods for azaindole synthesis is surveyed.
Explanation of Different Regioselectivities in the ortho‐Lithiation of Ferrocenyl(phenyl)methanamines
Diastereoselective ortho-lithiation of ferrocenes is a principal strategy for the synthesis of chiral ferrocene ligands. Dilithiation of (R)-1-(2-bromophenyl)-1-ferrocenyl-N,N-dimethylmethanamine
