The new reduction reaction of the hydroxy groups of 4-hydroxy-4-phenyl-1,2,3,4-tetrahydroisoquinolines (1) to the corresponding alkanes (2) with mineral and Lewis acids is reported. A stereoselective intermolecular hydride shift mechanism of the reduction was proved by reaction of the deuterated derivateives (14 and 15) of 1a with 10N HCl-C2H5OH and BBr3 in CH3CN.
A New Synthesis of 7,12-Dihydro-12-phenyl-5H-6,12-methanodibenz[c,f]azocines via N-Benzyl-1,2,3,4-tetrahydro-4-phenylisoquinolin-4-ols
摘要:
7,12-Dihydro-12-phenyl-5H-6,12-methanodibenz[c,f]azocine derivatives were prepared from N-benzyl-1,2,3,4-tetrahydro-4-phenylisoquinolin-4-ols by an intramolecular Friedel-Crafts reaction.
