224. Note on Attempts to Prepare Ring-B Homomorphinan-6-ones by Grewe Cyclization from Octahydro-1-phenethylisoquinolines

Dumont, Raymond,Pfander,Hanspeter,Brossi, Arnold

, p. 2128 - 2131 (2007/10/02)

Grewe cyclization of the N-formyl-protected octahydroisoquinolin-6-one 1 prepared by conventional chemistry did not afford the expected homomorphinanone.The exclusive reaction product obtained in good yield was the α,β-unsaturated N-formyloctahydroisoquinolin-6-one 2, further converted by acid hydrolysis into the crystalline octahydroisoquinolin-6-one 8.
