A one-pot, three-component synthesis of widely substituted isoindolinones and isoquinolinones, featuring a Lewis acid-catalyzed efficient Strecker reaction and lactamization sequence, affording products in good to high yields is reported. The method has also been extended to the synthesis of tetrahydroisoquinolines (THIQs) in high yields. (Chemical Equation Presented).

The aza-Henry reaction of 3,4-dihydroisoquinoline is reported. The reaction is favourable in excess nitromethane under ambient conditions. Isolation of the unstable reaction product is achieved by acylation or alkylation, allowing the synthesis of Reissert-like compounds in good yields from a one-pot, three-component coupling. The rates of reaction for dihydroisoquinoline and the corresponding benzylisoquinolinium ion have been investigated in the presence and absence of base. The reaction with dihydroisoquinoline probably proceeds via an azinic acid tautomer of nitromethane, a reaction pathway unavailable to the isoquinolinium ion. The traditionally problematic reduction of two of the resulting β-nitroamine derivatives was achieved, providing access to a number of new chiral vicinal diamines. 3,4-Dihydroisoquinoline reacts with nitromethane, likely via a cyclic mechanism employing nitromethane's azinic acid tautomer. The product may be alkylated or acylated. Alternatively a Reissert-like one-pot, three-component coupling may be used to generate a range of β-nitroamines which may be reduced to give new isoquinoline-derived chiral, vicinal diamines.

An improved synthesis of 1-(aminomethyl)-1,2,3,4-tetrahydroisoquinolines has been developed by using aluminum hydride reduction of 1-cyano-1,2,3,4-tetrahydroisoquinolines.Three 1-(aminomethyl)-6,7-dihydroxytetrahydroisnolines
