Photochemical synthesis of spirocyclohexylisoquinolines, analogues of (±)-galanthamine and (±)-lycoramine

Missoum, Assia,Sinibaldi, Marie-Eve,Vallee-Goyet, Danielle,Gramain, Jean-Claude

, p. 453 - 466 (1997)

Photocyclization of N-arylenamides 10, 15 and 16 led efficiently to spirotricyclic δ-lactams 5, 6 and 7. Compound 7 was easily and stereospecifically transformed in two steps into spirocyclohexylisoquinolines 3 and 4 which show structural analogies with some Amaryllidaceae alkaloids, galanthamine 1 and lycoramine 2.
