Asymmetric synthesis of ferrocenyl-substituted pyrrolidine derivatives was successfully achieved by diethylzinc-mediated 1,3-dipolar cycloaddition reactions of chiral azomethine ylides with a number of electron-deficient dipolarophiles. Chiral azomethine ylides were formed by condensing glycyl sultam with ferrocenecarboxaldehyde via imine tautomerization and complexation with diethylzinc. All of the cycloaddition reactions gave ferrocenyl-substituted pyrrolidine derivatives with very high regio- and diastereoselectivity in reasonable yields.

Dimethyl ether from syngas and effect of CO2 sorption on product distribution over a new bifunctional catalyst pair containing STA@SBA-15
ÇELİK ÖZCAN, MERVE; PEKMEZCİ KARAMAN, BİRCE; OKTAR, NURAY; Doğu, Timur (2022-12-01)
Direct synthesis of dimethyl ether (DME) from syngas was investigated in the presence of a bifunctional catalyst pair containing silicotungstic acid (STA) incorporated SBA-15 (5, 10, 25% by wt. STA) for the in-situ dehydration of synthesized methanol. The methanol synthesis component of this catalyst mixture is a Cu/ZnO-based commercial (HF) catalytic material. The new STA@SBA-15 type solid acid catalysts synthesized in this study indicated ordered mesoporous structures with surface area values in the range...
Auxiliary mediated synthesis of aziridine 2 carboxylic acid derivative
GARNER, Philip; Doğan, Özdemir; PİLLAİ, Satish (1994-03-01)
A convenient protocol for the asymmetric synthesis of stereodefined aziridine-2-carboxylic acid derivatives from alpha,beta-unsaturated acryloyl- and crotonoyl camphor sultams is reported.
Asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohol derivatives and applications in various asymmetric transformation reactions
Odabaş, Serhat; Tanyeli, Cihangir; Department of Chemistry (2007)
The asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohols and their applications in asymmetric borane reduction and enantioselective diethylzinc addition to benzaldehyde reactions were performed starting from meso-anhydride 51 that is the cycloadduct of cyclopentadiene and maleic anhydride. The desymmetrization of meso-anhydride 51 was achieved by using quinine or quinidine with very high enantiomeric excess value (up to 98% ee) and with high chemical yield. The quinine-mediated desymmetrizati...
Viscoelastic properties of reactive and non-reactive styrene-maleic anhydride olefinic blends
Bayram, G; Yılmazer, Ülkü; Xanthos, M (2000-05-11)
Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive...
Asymmetric synthesis of norbornene based 1,4-Aminoalcohol derivatives and applications in asymmetric diethylzinc reactions
Erdem, Mine; Tanyeli, Cihangir; Department of Chemistry (2007)
The asymmetric synthesis of chiral norbornene based 1,4-aminoalcohols and their applications in asymmetric diethylzinc addition reactions was perfomed starting from meso-anhydride 50. The desymmetrization of this meso-anhydride 50 was done by the usage of quinine or quinidine cinchona alkaloids with very high enantiomeric excess values (up to 98% ee) and chemical yields. The Quinidine-mediated desymmetrization of meso-anhydride 50 with methanol gave (2R,3S)-(+)-cis-monoester 51. The amination of this result...
