C. Shih et Y. Hu, A SHORT AND EFFICIENT SYNTHESIS OF ECHIGUANINE-A AND ECHIGUANINE-B - POTENT INHIBITORS OF PHOSPHATIDYLINOSITOL-4-KINASE, Tetrahedron letters, 35(27), 1994, pp. 4677-4680
An efficient synthesis which utilizes a palladium catalyzed carbonylat
ion reaction between 2-pivaloyl-7-iodo-7-deazaguanine and 3-aminopropi
onitrile as a key step was developed for the preparation of a new clas
s of pyrrolopyrimidine based PI 4-Kinase inhibitors: Echiguanines A an
