Oxidation Potential-Guided Electrochemical Radical-Radical Cross-Coupling Approaches to 3-Sulfonylated Imidazopyridines and Indolizines

Oxidation potential-guided electrochemical radical-radical cross-coupling reactions between N-heteroarenes and sodium sulfinates have been established. Thus, simple cyclic voltammetry measurement of substrates predicts the likelihood of successful radical-radical coupling reactions, allowing the simple and direct synthetic access to 3-sulfonylated imidazopyridines and indolizines. The developed electrochemical radical-radical cross-coupling reactions to sulfonylated N-heteroarenes boast the green synthetic nature of the reactions that are oxidant- and metal-free.

Mechanochemical Synthesis of 1,2-Diketoindolizine Derivatives from Indolizines and Epoxides Using Piezoelectric Materials

A simple and efficient mechanochemical-induced approach for the synthesis of 1,2-diketoindolizine derivatives has been developed. BaTiO3 was used as the piezoelectric material in this transformation. This method features no usage of solvent, simple experimental operation, scalable potential, and high conversion efficiency, which make it attractive and practical.

Visible-Light-Induced Regioselective Dicarbonylation of Indolizines with Oxoaldehydes via Direct C-H Functionalization

A metal-free system for regioselective dehydrogenative cross-couplings between indolizines and oxoaldehydes catalyzed by visible light under mild conditions has been described. As an atom economical and eco-friendly protocol, the reaction proceeds in good yields using inexpensive, readily available visible-light sources and the environmentally friendly oxidant oxygen. Various valuable 1,2-dicarbonyl derivatives attached to an indolizine core were easily accessed by the direct dicarbonylation of the sp2 C-H bond.

Controlling chemoselectivity-application of DMF di-t-butyl acetal in the regioselective synthesis of 3-monosubstituted indolizines

Among a number of DMF dialkyl acetals investigated for the regioselective synthesis of 3-acylindolizines, the di-t-butyl acetal, via its iminium intermediate readily formed in situ, provides the highest chemoselectivity for the intermolecular cyclization of picolinium salts. DMF di-t-butyl acetal was applied to the syntheses of a variety of 3-acylated indolizines including alkyl, aryl, and heteroaryl substituents.
