1. Purines. L. Synthesis and antileukemic activity of the antibiotic guanine 7-oxide and its 9-substituted derivatives
K Ogawa, M Nishii, J Inagaki, F Nohara, T Saito, T Itaya, T Fujii Chem Pharm Bull (Tokyo). 1992 Feb;40(2):343-50. doi: 10.1248/cpb.40.343.
A full account is given of the first chemical synthesis of the antitumor antibiotic guanine 7-oxide (5) and its 9-substituted derivatives (24a--k and 26). Coupling of appropriate primary amines (17a--e, g--k) with phenacyl bromide (16) produced, after treatment with HCl, the corresponding N-substituted phenacylamine hydrochlorides (18a--e, g--k). A similar phenacylation of 4-amino-l-butanol (21) failed to give the desired compound 18f, so that 21 was heated with 2-bromomethyl-2-phenyl-1,3-dioxolane (20) at 150-155 degrees C for 3h to furnish, after treatment with HCl, the amino ketal hydrochloride 22 in 40% yield. Deketalization of 22 with hot 2 N aqueous HCl afforded 18f in 96% yield. Condensations of the free bases, generated in situ from the hydrochlorides 18a--l and 1N aqueous NaOH, with the chloropyrimidinone 6 were effected in aqueous EtOH at the boiling point for 20 min or at 25-30 degrees C for 3-24h, giving the 6-phenacylamino-4-pyrimidinones 19a-l in 54-90% yields. On treatment with 2N aqueous NaOH at room temperature for 10-60 min, the nitropyrimidinones 19a--k cyclized to provide the 9-substituted guanine 7-oxides 24a--k in 61-98% yields. A similar alkali-treatment of 191 failed to yield guanine 7-oxide (5). However, removal of the 9-(arylmethyl) group from 24i--k was effected with conc. H2SO4 at room temperature for 1-3h in the presence of toluene, producing the target N-oxide 5 in 56-89% yields.
