Reduction of alcohols Ia and IIa with zinc and formic acid afforded 1-isopropylisoquinoline (Ib) and 1-cyclohexylisoquinoline (IIb), respectively, reduction with sodium in 1-butanol led to the 1,2,3,4-tetrahydroisoquinoline derivatives III, IV and Va and electrolytical reduction gave 1-isopropyl-1,2,3,4-tetrahydroisoquinoline (Vd) and the 1-cyclohexyl derivative Ve, respectively.
