New focused microwave approach to the synthesis of amino-substituted pyrroloisoquinolines and pyrroloquinolines via a sequential multi-component coupling process

A multi-component reaction has been developed allowing direct access to pyrroloisoquinolines and pyrroloquinolines with new, electron-rich substitution patterns. The synthesised amino-substituted heterocyclic compounds and intermediates involved in their formation represent novel compounds. Focused microwave irradiation was used extensively to allow simple access to a wide temperature range using low boiling point solvents.
