SYNTHESIS OF SOME IMIDAZO [ I , 2-b] [l , 2,4] TRIAZINE AND N-ALKYLATED IMIDAZO [l , 2-b] [1 , 2,4]-TRIAZINES
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 کاملPyridinium N-(20-azinyl)aminides: regioselective synthesis of N-(2-pyridyl) substituted polyamines
The regioselective alkylation of pyridinium-N-(20-pyridyl)aminide with alkyl dihalides under mild conditions, followed by N–N bond reduction of the corresponding bis-salts, allowed an easy preparation of N,N0-bis(2-pyridyl)diamines. The same methodology has been applied to the synthesis of N,N0,N00-tris(2-pyridyl)triamines. q 2002 Elsevier Science Ltd. All rights reserved. The role of polyamine...
متن کاملA convenient synthesis of N,N'-dibenzyl-2,4-diaminopyrimidine-2'-deoxyribonucleoside and 1-methyl-2'-deoxypseudoisocytidine.
The syntheses of N,N'-dibenzyl-2,4-diaminopyrimidine-2'-deoxyribonucleoside and 1-methyl-2'-deoxypseudoisocytidine via Heck coupling are described. A survey of the attempts to use the Heck coupling to synthesize N,N'-dibenzyl-2,4-diaminopyrimidine-2'-deoxyribonucleoside is provided, indicating a remarkable diversity in outcome depending on the specific heterocyclic partner used.
متن کاملSynthesis of 1- and 4-substituted piperazin-2-ones via Jocic-type reactions with N-substituted diamines.
Enantiomerically-enriched trichloromethyl-containing alcohols, obtained by asymmetric reduction, can be transformed regioselectively into 1-substituted piperazinones by modified Jocic reactions with little or no loss of stereochemical integrity. This methodology can be easily used to synthesise important pharmaceutical compounds such as the fluorobenzyl intermediate of a known PGGTase-I inhibitor.
متن کاملConvenient access to readily soluble symmetrical dialkyl-substituted α-oligofurans.
An expedient approach to the synthesis of well soluble symmetrical dialkyl-substituted α-oligofurans containing up to 8 π-conjugated furan heterocycles is reported. An ultimate symmetry and high solubility of these α-oligofurans were guaranteed using the 3,3'-diheptyl-2,2'-bifuran core and its symmetrical elongation through Suzuki-Miyaura or Stille cross-couplings. 3,3'-Diheptyl-2,2'-bifuran wa...
