SYNTHESIS OF SELENAZOL0[3,2-b] [ 1,2,4] TRIAZINE AND SELENAZOLO [2,3-C] [I ,2,4] TRIAZINE
نویسندگان: ثبت نشده
چکیده مقاله:
6-Methyl- 1,2,4-triazine-3-(2H)-selenone-5(4H)-one(l) reacts in the presence of base with phenacyl bromide to give a mixture of compounds (2) and (3). This mixture is dehydrated in the presence of H,SO, to give 3-phenyl-6 methyl-7H-selenazolo[3,2-b] [I ,2,4] triazin-7-one (6). For careful structure assignment of (6) its regioisomer 3-methyl-6-phenyl-4H-selenazolo [2,3-c] [ 1,2,4] triazin-4-one (8) was unambiguously synthesized and its spectroscopic data were Compared with those of (6)

A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3).

متن کاملTraceless solid-phase synthesis of 6-amino- and 6-hydroxyimino-1,3,5-triazine-2,4-diones and 1,3,5-triazine-2,4,6-triones.
A traceless solid-phase synthesis of 6-amino- and 6-hydroxyimino-1,3,5-triazine-2,4-diones and 1,3,5-triazine-2,4,6-triones has been developed. The strategy comprises of linking a preformed N-carbamothioylcarbamate to bromomethyl resin to give a S-linked isothiourea, which then undergoes cyclization with isocynates to yield the resin-bound 1,3,5-triazine-2,4-diones. Subsequent cleavage was acco...
متن کاملEpisulfonium ion-mediated cyclic peptide and triazine synthesis.
The product of an episulfonium ion-mediated cyclotrimerisation, previously reported as being a 15-membered ring trilactam, has now been shown to be a 1,3,5-triazine. Smaller medium-ring bilactams have, however, been synthesised from linear precursors using the sulfur-based methodology.
متن کاملTriazine-dye affinity; chromatography.
functional resemblance of column groups to carbamoyl phosphate. The enzyme binds its two substrates, carbamoyl phosphate and L-aspartate, in an obligatory order, with carbamoyl phosphate leading (Grayson et al., 1979). If column groups are sufficiently similar to carbamoyl phosphate, the enzyme should be adsorbed more tightly in the presence of L-aspartate, owing to the ‘locking-on’ effect (O’C...
