Nucleobases, including 9-methyl-, 9-ethyl-, 1,9-dimethyl-guanine and 2-amino-6-methoxy-9-methylpurine, form complexes of the type Au(N)Cl3 when reacted with [AuCU] in water at pH 3—4. Binding of a AuCh unit to the N (7) position of the purine ring was confirmed by X-ray crystallography [26]. [Pg.50]

Amino-6-chloro-9-[2-(2,2-dimethyl-l,3-dioxan-5-yl)-ethyl]purine (0.59 g, 1.9 mmol) in hydrochloric acid (1.0 M, 4 ml) was stirred at 60°C for 24 hours. The solution was diluted with water and neutralised with Amberlite IR 45. The mixture was filtered, the resin washed with water and the solvent evaporated under reduced pressure. The residue was recrystallised from water to afford 9-(4-hydroxy-3-hydroxymethylbut-l-yl)guanine (238 mg, 49%), melting point 275°-277°C. [Pg.2637]

A new synthesis of purines is illustrated by the reaction of l,3-dimethyl-6-aminouracil with MiV-dimethyldichloromethyleneiminium chloride (phosgeneiminium chloride), trimethylsilyl azide and arylamines in dry chloroform, followed by treatment with 20% aqueous potassium hydrogen carbonate. The reaction probably proceeds via a 4-amino-5-(chloroformamidin-l -yl)uracil (Scheme 10) [94JHC1185],... [Pg.259]
