A one-pot isoquinoline synthesis by cyclodehydrogenation of N-benzyl-.ALPHA.-alkylaminoacetals with chlorosulfonic acid. Formation of 3-alkylisoquinolines.

Article 1987 EN Bronze

A direct preparation of fully aromatized 3-alkylisoquinolines (3e-p), was achieved by cyclodehydrogenation with chlorosulfonic acid of N-benzyl-α-alkylaminoacetals (2e-p) which were prepared by addition of Grignard reagent to N-benzyliminoacetals (1a-d).
