Description |
A general approach for the synthesis of 3H-pyrazolo[3,4-c]isoquinolines and thieno[3,2-c]isoquinolines is described involving the implementation of a cascade imination/ intramolecular decarboxylative coupling between potassium 2-amino(hetero)benzoates and 2-haloarylaldehydes. The reactions of pyrazole-based substrates require a Pd-Cu bimetallic system for superior yields whereas the thienyl-based substrates afford the products in excellent yields with Pd-catalyst only.
