Several hydroquinolyl alcohols and amines were electrochemically oxidized in methanol in the presence of sodium methoxide and potassium iodide to afford the corresponding intramolecular cyclization products. Furthermore, several amino malonates were electrochemically oxidized to yield the corresponding heterocyclic compounds through an intramolecular carbon–carbon bond formation in the presence of sodium cyanide in methanol.

In recent years, new processes based on transition-metal-mediated intramolecular addition reaction of heteronucleophiles and stabilized carbon nucleophiles to unactivated alkenes and alkynes have been developed in our laboratory. In this article, we summarize a number of recent synthetic applications of these new processes. Emphasis is placed on the development of multicomponent reactions based on a Pd-mediated intramolecular cyclization coupled with a carbon-carbon bond-forming reaction. Applications of this methodology to the synthesis of natural lignans are also reported.

The reaction between 4-thiaheptane-2,6-dione and 1,2-diaminobenzene in the presence of nickel(II) perchlorate results in the formation of a nickel(II) complex of a novel new heterotricyclic system: 1-methoxy-10-methyl-12-thia-2,9-diaza-tricyclo[8.3.1.03,8]tetradeca-3,5,7-triene, which on treatment with potassium cyanide gives 10-methy-12-thia-2,9-diaza-tricyclo[8.3.1.03,8]tetradeca-3,5,7-triene-1-carbonitrile, a case of metal-induced carbon–carbon bond formation.Key words: nickel-induced carbon–carbon bond formation, intramolecular cyclization, tricyclic formation.
