Biological activity of 6-substituted 4-methylpyrimidines

Biological activity of 6-substituted 4-methylpyrimidines. Karabanov, Yu. V.; Prikazchikova, L. P.; Zhuravskaya, N. I.; Rybchenko, L. I.; Cherkasov, V. M. (Inst. Org. Khim., Kiev, USSR). Fiziol. Akt. Veshchestva, 8, 99-101 (Russian) 1976. CODEN: FAVUAI. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Section cross-reference(s): 28 The title compds. I(R1=R2=H) [3438-46-8], I(R1=H, R2=Me) [1558-17-4], I(R1=H, R2=OH) [3524-87-6], I(R1=H, R2=NH2) [3435-28-7], and I(R1=R2=OH) [626-48-2] showed plant-growth stimulating activity in tests with lettuce and oat seedlings, whereas I(R1=H, R2=OMe) [5541-07-1], I(R1=H, R2=SH) [51793-97-6], 6-methylmercapto-4-methylpyrimidine [62671-89-0], and I(R1=SH, R2=Me) [13139-97-4] were plant-growth inhibitors. Synthesis of N-oxy-6-methylsulphonyl-4-methylpyrimidine (II) [62744-95-0] was given. II stimulated the growth of oats and inhibited that of lettuce.

Preparation of pyrimidin-4-ones from aminopropenoic acids or iminopropanoic acids

Preparation of pyrimidin-4-ones from aminopropenoic acids or iminopropanoic acids. Nishino, Shigeyoshi; Hirotsu, Kenji; Shima, Hideyoshi; Suzuki, Shinobu (Ube Industries, Ltd., Japan).Except for chemicals metioned above, 3524-87-6 is also used. Jpn. Kokai Tokkyo Koho JP 2006036708 A2 9 Feb 2006, 9 pp. (Japanese). (Japan). CODEN: JKXXAF. APPLICATION: JP 2004-220551 28 Jul 2004. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Pyrimidin-4-ones I [R0, R4 = H, hydrocarbyl; R1, R2 = (un)substituted inert group; R1R2 may be linked to form nonarom. ring] are prepd. by cyclocondensation of H2NCR2:CR1CO2R3 or NH:CR2CHR1CO2R3 (R1, R2 = same as above; R3 = H, hydrocarbyl) with R5C(OR4)3 [R4 = same as above; R5 = (un)substituted inert group] in the presence of ammonium of R0NH2 (R0 = same as above). Thus, Et 2-iminocyclopentanecarboxylate was treated with Me orthoformate and AcONH4 at 130° for 8 h in MeOH to give 83% 3,5,6,7-tetrahydrocyclopentapyrimidin-4-one. 3524-87-6 is the cas registry number. This chemical is also mentioned in this article. ..
