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.

An efficient transition-metal-free regioselective C-H/S-H cross-coupling of indolizines with thiols has been developed for the first time to describe a workable route to indolizine thioethers. This finding provides a new method and more straightforward pathway for controllable synthesis of mono- or dithiolation indolizines that are otherwise difficult to obtain by the literature methods. The reaction exhibits good functional group tolerance and high efficiency and affords the products in good to excellent yields.

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.
A Practical Parallel Synthesis of 2-Substituted Indolizines
Chai, Wenying,Kwok, Annette,Wong, Victoria,Carruthers, Nicholas I.,Wu, Jiejun
, p. 2086 - 2088 (2007/10/03)
A practical parallel synthesis of 2-substituted indolizines 4 via phase-separation techniques is reported. Their further transformation into indolizidines 5 is also described.
