A highly efficient catalytic asymmetric synthesis of 1,1-disubstituted tetrahydroisoquinolines has been achieved via asymmetric alkylation or Michael addition of 1-cyanotetrahydroisoquinolines using binaphthyl-modified N-spiro-type chiral phase-transfer catalysts.

It was found that 4-hydroxy-2-butenoic ester (11) could not react with 3,4-dihydro-isoquinoline (4a). Individual addition reactions of γ-mercapto-α,β-unsaturated esters (18) and -unsaturated amide (19) with 3,4-dihydroisoquinolines (4) were carried out under appropriate conditions to provide the corresponding thiazolo[2,3-α]isoquinoline derivatives with good yields (up to 87%) and significant diastereomeric
omnipresent in biologically active molecules. Here we report on the direct asymmetric synthesis of these valuable compounds via the reaction of 3,4-dihydroisoquinolinium tetraarylborates. The dualroles of anionic tetraarylborates, which function as both prenucleophiles and stabilizers of 3,4-dihydroisoquinolinium cations, enable this rhodium(I)-catalyzed protocol to convergently provide enantioenriched 1-aryl

α-methylene-γ-lactam products in good yields (up to 79%) as single diastereomers. The reactions proceed efficiently when AgOTf is used as an anion exchange catalyst with a 20 mol % loading at 80 °C. Computational studies were performed to investigate the reaction mechanism, and the findings support the role of the −TMS group in reducing the reaction barrier of the key cyclization step.
