A direct synthesis of 5,6-dihydroindolo[2,1-a]isoquinolines that exhibit immunosuppressive activity.
Bioorganic & medicinal chemistry letters, 19(19), 5539-5542 (2009-09-05)
Dihydroindolo[2,1-a]isoquinolines were synthesized from tetrahydroisoquinolines and alpha-fluoroaldehydes by a novel two-step procedure. These compounds exhibited significant immunosuppressive activity against IL-2, IL-10 and IFN-gamma.

Phosphazene superbase P4- t-Bu mediated iodoaminocyclization of 2-(1-alkynyl)benzamides is reported. The reaction works under ambient conditions and instantaneously results in the synthesis of isoindolin-1-ones in 65-97% yields, in a regio- and stereoselective manner.
