A convenient synthesis for new SCH 23390 analogues bearing different substituents at the C-1 position has been developed by using the diastereoselective Stevensrearrangement. This procedure has provided a good number of new 1,2-disubstituted 1H-3-benzazepines, either through isolation of the isoquinolinium salts or directly by using a new one-pot N-alkylation–Stevens rearrangement reaction.

Cyanomethyl-substituted tetrahydroisoquinolines and tetrahydrothieno[3,2-c]pyridines were synthesized by multicomponent reaction of the dihydro analogues of aforesaid systems with benzyne and acetonitrile. The products obtained relate to alkaloids of isoquinoline family of 1,2,3,4-tetrahydro level.
