Application of primary halogenated hydrocarbons for the synthesis of 3-Aryl and 3-Alkyl indolizines

Indolizine is an important heterocyclic compound with several interesting properties that make it suitable for numerous applications in many fields, such as biology, medicine and materials. However, the synthesis of 3-Alkyl indolizines from bulky primary halogenated alkanes has not yet been reported. Herein, a transition-metal-free synthetic route to 3-Aryl and 3-Alkyl indolizines from electron-deficient alkenes, pyridines and primary halogenated hydrocarbons has been reported for the first time using a tandem reaction. The key step of this method is the oxidative dehydrogenative aromatization of a tetrahydroindolizine intermediate with 2,2,6,6-Tetramethylpiperidine-N-oxyl (TEMPO) as the oxidant. The advantages of this protocol are its use of easily available and low-cost starting materials, the transition-metal-free conditions and its ready scalability.

Electrochemical Reactions. Part 26. Radicals Derived by Reduction of N-Alkylpyridinium Salts and Homologous N,N'-Polymethylenebispyridinium Salts. Cleavage of the Carbon-Nitrogen Bond

The stability of the radical zwitterions derived by electron addition to N-alkyl-2,4,6-triphenyl- and 4-phenylpyridinium salts has been examined.Rapid carbon-nitrogen bond cleavage occurs for benzyl and allyl substituents only when the 2,6-diphenyl substituents are present.The N-propyl group is not lost.Homologous N,N'-polymethylenebis(2,4,6-triphenylpyridinium) salts show two reversible one electron waves, distinct for the ethylene derivative and merging as the carbon chain lengthens so that ΔEo reaches the theoretical value of (RT/F) ln 4.
