ChemInform Abstract: Construction of Functionalized Tricyclic Dihydropyrazinoquinazolinedione Chemotypes via an Ugi/N‐Acyliminium Ion Cyclization Cascade. Issue 47 (4th November 2013) - Gunawan, Steven
Abstract The substitution of the fluorine group in the Ugi adduct (V) by primary amines (VI) followed by a microwave‐promoted double cyclization affords the desired tricyclic derivatives (VII) as a single diastereomer.
