Development of New C-N Bond Forming Reactions
Nitrogen containing organic molecules have attracted much attention as bioactive compounds and functional materials. In our group are currently focused on the chemical reactivity of some nitrogen-containing small molecules such as organic azides and oxime derivatives, and their chemical activation for generation of nitrogen reactive species like metal-nitrene complexes, iminyl metal species, and iminyl radicals. Such chemical species would lead to the development of unprecedented C-N bond forming reactions. The products synthesized by these reactions are especially important in medicinal, agricultural, and natural product chemistry as well as in the material science.

For example, a Mn(III)-mediated divergent synthesis of substituted pyridines and 2-azabicyclo[3.3.1]non-2-en-1-ol derivatives was exploited using readily available vinyl azides and cyclopropanols with a wide range of substituents. The reactions of vinyl azides with monocyclic cyclopropanol provided pyridines in the presence of Mn(acac)3, whereas those with bicyclic cyclopropanols led to the formation of 2-azabicyclo[3.3.1]non-2-en-1-ol derivatives using a catalytic amount of Mn(acac)3. These reactions may be initiated by a radical addition of -keto radicals, generated by the one-electron oxidation of cyclopropanols, to vinyl azides to give iminyl radicals, which would cyclize with the intramolecular carbonyl groups.

Mn Acac 3 Preparation - Essay by Giasulchemist

Intramolecular oxidative coupling with Mn(acac) has been used as a key step in the synthesis of (+)- and (-)-galanthamine (eq 2). Mn(acac) induces the oxidative cyclization of a phenolic oxime to give the spiroisoxazoline in 50% yield (eq 3). Mn(acac) in carbon disulfide oxidizes aryl, alkyl, and benzyl thiols at rt in 1-2 h to disulfides in 85-99%

Experiment 12--The Magnetic Susceptibility of Mn(acac)3

AB - The interaction of tris(acetylacetonato)manganese(III), Mn(acac)3, with methyl-lithium in the presence of 1,2-bis(dimethylphosphino)ethane (dmpe) in diethyl ether leads, in a disproportionation reaction, to MnMe2(dmpe)2 and to Mn Me 4(dmpe) whose X-ray structure has been determined; also synthesised from Mn (acac)3 are MnMe4(PMe3)2 and the green tetrahedral alkyl complexes MnR4, R = CH2SiMe3 and CH2CMe3 which have been identified spectroscopically.

In short, the reactions of vinyl azides with monocyclic cyclopropanol provided pyridines in the presence of Mn(acac)3 (1.7 equiv), whereas those with bicyclic cyclopropanols led to the formation of 2-azabicyclo[3.3.1]non-2-en-1-ol derivatives using a catalytic amount of Mn(acac)3.

This study focused on the synthesis, characterization and cytocompatibility of a biodegradable polymer by the cross-linking from poly(ethylene glycol-co-lactide) dimethacrylate (PLEGDMA), polyethylene glycol diacrylate (PEGDA) and N-isopropylacrylamide, where PLEGDMA was synthesized by ring-opening oligomerization of poly(ethylene glycol) with different molecular weights (Mn = 400, 600, 1000, 2000 Da) and -lactide using low toxic iron(III) acetylacetonate (Fe(acac)3) as the catalyst and subsequently being terminated with dimethacrylate. The product, PLEGDMA, was analyzed to confirm its chemistry using FTIR spectroscopy, 1H NMR spectra and gel permeation chromatography etc. The thermodynamic properties, mechanical behaviors, surface hydrophilicity, degradability and cytotoxicity of the cross-linked product were evaluated bydifferential scanning calorimetry, tensile tests, contact angle measurements and cell cultures. The effects of reaction variables such as PEGDA content and reactants ratio were optimized to achieve a material with low glass transition temperature (Tg), high wettability and preferable mechanical characteristics. Using a tubular mould which has been patented in our group, a tubular scaffold with predetermined dimension and pattern was fabricated, which aims at guiding the growth and phenotype regulation of esophageal primary cells like fibroblast and smooth muscle cell towards fabricating tissue engineered esophagus in future.
