  Research in the field of imidazo[1,2-a]benzimidazole derivatives: XXVII. 1-acylmethyl-2-(ω-hydroxyalkylamino)-benzimidazoles and their transformation into derivatives of tricyclic systems

  摘要：

  1-Acylmethyl-2-(omega-hydroxyalkylamino)benzimidazoles were synthesized and their behavior under various conditions was investigated: at the thermolysis without solvent, at heating in DMF or in 2-aminoethanol, hydrohalic acids, and acetic anhydride, in the presence of chlorinating agents (SOCl(2), POCl(3)). Depending on the reaction conditions derivatives were obtained of 1H-imidazo[1,2-a]-benzimidazole, 9H-2,3-dihydroimidazo[1,2-a]benzimidazole, and 10H-2,3,4,10-tetrahydropyrimido[1,2-a]-benzimidazole that were suitable synthons for the synthesis of functionally substituted derivatives of these tricyclic systems.

• Direct Conversion of Primary Alcohols to 1,2-Amino Alcohols: Enantioselective Iridium-Catalyzed Carbonyl Reductive Coupling of Phthalimido-Allene via Hydrogen Auto-Transfer

  primary alcohols 2a-2z, 2a'-2c' engage in hydrogen auto-transfer-mediated carbonyl reductive coupling by way of (α-amino)allyliridium-aldehyde pairs to form vicinal amino alcohols 3a-3z, 3a'-3c' with high levels of regio-, anti-diastereo-, and enantioselectivity. Reaction progress kinetic analysis and isotopic labeling studies corroborate a catalytic cycle involving turnover-limiting alcohol dehydrogenation

  New preparation method was developed for derivatives of 1,4-dihydro-1,2,4-triazino[4,3-a]-, 2-aryl-1(9)H-, and 1-R-imidazo[1,2-a]benzimidazole underlain by newly synthesized 1-acylmethylbenzimidazole-2-sulfonic acids. The latter react with 2-aminoethanol affording along with the previously described compounds of the 1-(2-hydroxyethyl)imidazobenzimidazole series also compounds of formerly unknown polycyclic system, 2,3,11,12-tetrahydro-1,3-oxazolo[2,3-a]imidazo[1,2-a]benzimidazole.
