Phosphazene Bases

Phosphazene base reagents are available as monomeric (P1 and BEMP), dimeric (P2), and tetrameric (P4) bases with different side chains to control their sterical hindrance.

Phosphazene Superbase-Mediated Regio- and Stereoselective Iodoaminocyclization of 2-(1-Alkynyl)benzamides for the Synthesis of Isoindolin-1-ones.

Saurabh Mehta et al.

The Journal of organic chemistry, 84(9), 5492-5503 (2019-04-16)

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. The exclusive formation of products with Z-geometry

A direct synthesis of 5,6-dihydroindolo[2,1-a]isoquinolines that exhibit immunosuppressive activity.

George A Kraus et al.

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.
