Synthesis of 8-substituted pyrazolo[1,5-a]-1,3,5-triazine derivatives by palladium-catalyzed cross-coupling reactions

Popowycz, Florence,Bernard, Philippe,Raboisson, Pierre,Joseph, Benoit

, p. 367 - 374 (2008/01/06)

8-Substituted pyrazolo[1,5-a]-1,3,5-triazine derivatives 6 were prepared from the corresponding 8-iodopyrazolo[1,5-a]-1,3,5-triazines 5 through palladium-catalyzed cross-coupling reactions. Several bioisosteres of hypoxanthine drugs 2 were then prepared b
