Direct Enamido C(sp2)?H Diphosphorylation Enabled by a PCET-Triggered Double Radical Relay: Access to gem-Bisphosphonates

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp2)?H diphosphorylation. This reaction represents a rare example of realizing the challenging double C?P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

Iron-Catalyzed Radical Cycloaddition of 2H-Azirines and Enamides for the Synthesis of Pyrroles

A novel and efficient Fe-catalyzed radical cycloaddition of 2H-azirines and enamides for the synthesis of substituted pyrroles has been developed. The radical cycloaddition reaction proceeded through a conceptually new Fe(II)-catalyzed homolytic cleavage of C-N bond of 2H-azirines sequential radical cyclization with enamides. The reaction used readily available starting materials, tolerated various functional groups, and afforded valuable triaryl-substituted pyrroles in good to high yields under mild reaction conditions.

Transition metal complex, chiral alpha-amino tertiary borate and preparing methods thereof

The invention discloses a transition metal complex, chiral alpha-amino tertiary borate and preparing methods thereof. The chiral alpha-amino tertiary borate preparing method comprises the step of mixing a compound II, a metal ligand complex and bis(pinaco

One-pot green synthesis of enamides and 1,3-diynes

A green organic synthetic method combining reductive acylation of ketoximes and oxidative coupling of terminal alkynes was developed. This novel process enables enamides and 1,3-diynes to be synthesized simultaneously in high yields and under mild conditions without the use of terminal reductants/oxidants.

Synthesis of chiral α-amino tertiary boronic esters by enantioselective hydroboration of α-arylenamides

The rhodium-catalyzed asymmetric hydroboration of α-arylenamides with BI-DIME as the chiral ligand and (Bpin)2 as the reagent yields for the first time a series of α-amino tertiary boronic esters in good yields and excellent enantioselectivities (up to 99% ee).

Copper-promoted oxidative coupling of enamides and alkynes for the synthesis of substituted pyrroles

An efficient copper-promoted oxidative coupling of enamides with alkynes has been developed for the synthesis of substituted pyrroles. The reaction proceeded through C-H and N-H bond functionalization of enamides under mild conditions.

Pd-catalyzed Oxidative coupling of Enamides and Alkynes for synthesis of substituted Pyrroles

A novel and efficient palladium(II)-catalyzed alkenyl C-H activation oxidative annulation of enamides with alkynes for the synthesis of substituted pyrroles has been developed. The reaction tolerates a wide range of functional groups and is a reliable method for the synthesis of triaryl-substituted pyrroles in high yields.

Coupling of enamides with alkynes or arynes for synthesis of substituted pyridines and isoquinolines via amide activation

A novel and general procedure for Cu-catalyzed coupling of enamides with alkynes to synthesize substituted pyridines was developed. The chemistry was allowed to extend to the synthesis of substituted isoquinolines by coupling of enamides with arynes under transition-metal-free conditions.

Synthesis of enamides via CuI-catalyzed reductive acylation of ketoximes with NaHSO33

CuI-catalyzed reductive acylation of ketoximes for preparation of enamides was reported. A broad scope of enamides was obtained in high yields with NaHSO3 used as the terminal reductant.
