摘要

A range of tertiary N-allylamines derived from 1, 2, 3, 4-tetrahydroisoquinoline undergo oxidative cyclisation, induced by Ag2CO3, to pyrrolo-dihydroisoquinolines in moderate to good yield. Analogous oxidative cyclisations are reported for N-allyl-tetrahydro-β-carbolines and a pyrrolidine. The reactions proceed via formation of a 1, 5-dipole followed by an electrocyclisation and subsequent aromatisation.
