We have reported here a facile stereoselective synthesis of julolidine hybrid analogs by employing domino Knoevenagel intramolecular hetero Diels–Alder reaction on symmetrical 1,3-diones and unsymmetrical 1,3-diones It was found that the cycloaddition proceeded efficiently under microwave irradiation to afford highly stereoselective cycloadducts in good yields

A new methodology is developed for the efficient synthesis of 1,3-diketone-linked N-substituted pyrroles, pyrrolo[1,2-a]pyrazines, pyrrolo[1,4]diazepines, and pyrrolo[1,4]diazocines in good yields via a Yb(OTf)3-catalyzed, nitromethane-mediated reaction of primary amine/diamine, furfural, and 1,3-diketone. Possible mechanisms for these multicomponent reactions are also proposed.
