2- pyrimido pyrimidine

Bellido, L, de la Cruz, J.P. and de la Cuesta, S. (1991). The pyrimido pyrimidine derivative RA642 a potent inhibitor of ferrous induced lipid peroxidation. Meth. Find. Exp. Clin. Pharmacol. 13, 371-375. [Pg.274]

Pyrimido[4,5- f]pyrimidines may be used as pyrimidine precursors. Thus, the dihydro derivative (736) undergoes alkaline hydrolysis to the amide (737 R = PrCO) which may be deacylated in ethanolic hydrogen chloride to give 5-aminomethyl-2-propylpyrimidin-4-amine (737 R = H) (64CPB393) rather similarly, the pyrimidopyrimidinedione (738) reacts with amines to give, for example, 6-amino-5-benzyliminomethyl-l,3-dimethylpyrimidine-2,4(lFf,3Ff)-dione (739 R = CH2Ph) or the hydrazone (739 R = NH2) (74JCS(Pl)1812). [Pg.122]

The 3- or 5-aminopyrazoles are the synthons used most frequently. The second heterocyclic ring is created between the amino group and the 1-position (if unsubstituted) or between the amino group and the 4-position. Thus 3-substituted 5-aminopyrazoles react with 1,3-difunctional compounds to afford pyrazolo[l,5-a]pyrimidine derivatives (538) (Table 34). Aminopyrazolinones (R = OH) can be used instead of aminopyrazoles. Similarly 3-aminoin-dazole yields pyrimido[l,2-h]indazoles (539). [Pg.271]
