Chemistry of Organic Polyheterocyclic Conductors
Israel Journal of Chemistry, 1986AbstractThe synthesis and some properties of polymeric heterocycles as well as the latest results in the area of soluble conducting polymers are reviewed. Polyheterocycles with long chain substituents exhibit unusual properties in solution while retaining a relatively high conductivity in the solid state.

A novel polyheterocyclic chemical space, 6H-furo[3,2-f]pyrrolo[1,2-d][1,4]diazepine, was generated by a one-pot four-component coupling reaction where multiple bonds (three C-C, one C-O, and one C-N) were formed through a domino sequence.

New processable low band-gap, conjugated polyheterocycles
Synthetic Metals, 1993Abstract Poly(2,3-dihexylthieno[3,4-b]pyrazine) (2b) has been prepared by ferric chloride polymerization of 2,3-dihexylthieno[3,4-b]pyrazine(4) and studied. It is a dark blue-black soluble material which becomes light yellow in the doped state as either a solution or film. Doped films can be cast directly from solution.

Substrate-controlled switchable asymmetric annulations to access polyheterocyclic skeletons
Chemical Communications, 2016Substrate-controlled switchable asymmetric annulations of Morita–Baylis–Hillman carbonates from isatins and α-cyano-α,β-unsaturated ketones catalysed by cinchona-derived tertiary amines, giving tetrahydrofuro[2′,3′:4,5]pyrano[2,3-b]indoles or spirooxindoles incorporating a cyclopentene motif, were disclosed.

Synthesis and antifungal activities of novel polyheterocyclic spirooxindole derivatives
Organic & Biomolecular Chemistry, 2015A series of spirooxindole tetrahydrofuran derivatives were obtained in moderate to good yields via base-mediated cascade [3+2] double Michael reactions under mild conditions. Their antifungal effects on selected five target phytopathogenic fungi were investigated, and their structure antifungal activity relationships were also discussed.

Polyheterocyclic conductors from N-(ortho-substituted phenyl)pyrroles
J. Chem. Soc., Chem. Commun., 1983Voltammetric studies are reported which show that both electronic and steric effects are important in the electrosynthesis of organic metal films from N-(ortho-substituted phenyl)pyrroles in agreement with n.m.r. studies reported by other workers; the resulting films employed as electrodes yield well defined cyclic voltammograms similar to those ...

Silver‐Catalyzed Carbon‐Phosphorus Functionalization for Polyheterocycle Formation
Advanced Synthesis & Catalysis, 2017AbstractPolyheterocycle construction with high diastereoselectivity by utilizing a radical process is still problematic. In this communication, a silver‐catalyzed carbon‐phosphorus functionalization for polyheterocycle formation is described that furnishes good diastereoselectivity.
