    Kinetic resolution of (±)-4-acyloxytetrahydroisoquinolines (5-7) by use of lipases immobilized on Celite in isooctane or cyclohexane saturated with water was carried out to give 4S-(+)-tetrahydroisoquinolin-4-ol (8) in a high optical purity. The absolute configuration of (+)-8 was determined by comparison of the spectral data and specific rotation with those of authentic 4R-(-)-tetrahydroisoquinolin-4-ol (8) derived from R-(-)-epinephrine (9).

    trifluoroacetic acid yields three types of products: N,N-dimethylphenylethanolamines, N,N-dimethylphenethylamines, and tetrahydroisoquinolines, depending on the substituents in the aromatic ring and reaction conditions. Moreover, an additional step of oxazolidine hydrolysis or ring-opening with hydrogen cyanide allowed us to synthesize N-methyl- or N-methyl-N-(cyanomethyl)phenethylamines.
