XYZH systems as potential 1,3-dipoles. Part 36. 1,5-Electrocyclisation processes via oxidation of tertiary amines. Pyrrolo-dihydroisoquinolines and -dihydro-β-carbolines.
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-beta-carbolines and a pyrrolidine. The reactions proceed via formation of a 1,5-dipole followed by an electrocyclisation and subsequent aromatisation.
