Schiff bases electroreductive cyclization

Schiff bases have been used in electroreductive cyclizations, leading to heterocyclic compounds. The bisimine (24), when reduced in glyme, affords the piperazine (25) in 42% yield after quenching with methyl iodide (equation 10). When the solvent is changed to dimethylformamide, saturation of the imino bonds takes place without ring closure. Transannular ring closure of diazocine (26) led to indolo-... [Pg.136]
