Synthesis of 5,6,6a,7,7a,12a-Hexahydro-4H-benzobenzothienoquinolines and of 8-Phenyl-2,3,7,8,9,9a-hexahydro-1H-benzoquinolines

Demethylation of 1-(3-benzothienylmethyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline (1; R=H) gives two diastereoisomeric 1,2-dihydroxy-5,6,6a,7,7a,12a-hexahydro-4H-benzobenzothienoquinolines (4; R=H).Desulphurisation of their N-acetyl-di
