Sorting tags are oligomeric structures that can be used as protecting groups or chiral auxiliaries enabling solution-phase mixture syntheses of multiple tagged compounds in one pot and allowing for facile and predictable chromatographic separation of products at the end of synthetic sequences. Perfluorinated hydrocarbon and oligomeric ethylene glycol (OEG) derivatives are known classes of sorting tags. Herein we describe the preparation of OEGylated chiral oxazolidinones and their use in asymmetric solution-phase mixture aldol reactions. Through the use of such oxazolidinones based on tyrosine four different individually tagged aldol adducts were obtained as a mixture, chromatographically demixed, detagged, and it was shown that these processes gave the desired aldol products in good yield and enantioselectivity.

Asymmetric synthesis of 2,3-dihydrofurans with bifunctional quinine / squaramide organocatalysts Bozdemir, Merve; Tanyeli, Cihangir; Department of Chemistry (2019) Organocatalytic asymmetric reactions are efficient and environmentally friendly methods to synthesize products with higher enantioselectivities. Asymmetric domino Michael-SN2 reactions are one of the type of organocatalytic reaction frequently used to form carbon-carbon bonds in the synthesis of the derivatives of dihydrofurans, which are intermediates mainly utilized as precessor materials in the pharmaceutical fields. In this thesis, the reaction occuring between acetylacetone and (Z)-(2-bromo-2-nitroviny...
Oligomeric ethylene glycols as sorting tags for parallel and combinatorial mixture synthesis Wilcox, CS; Türkyılmaz, Serhan (Elsevier BV, 2005-03-14) Sorting tags for chromatography allow mixtures of substrates to be carried through parallel chemical processes and then separated. The first sorting tags were fluorocarbons. An enabling characteristic of fluorous sorting tags is the predictable incremental increase in retention time with increasing fluorocarbon chain length. Here we describe a general approach to sorting tags and report our discovery of a second class of chromatographic tags. The new tags are oligomeric ethylene glycol (OEG) derivatives.
Immobilization of dioxomolybdenum(VI) complex bearing salicylidene 2-picoloyl hydrazone on chloropropyl functionalized SBA-15: A highly active, selective and reusable catalyst in olefin epoxidation Bagherzadeh, Mojtaba; Zare, Maryam; Salemnoush, Taghi; Özkar, Saim; Akbayrak, Serdar (Elsevier BV, 2014-04-05) A novel organic-inorganic hybrid heterogeneous catalyst system was obtained from the reaction of the molybdenum(VI) complex of salicylidene 2-picoloyl hydrazone with mesoporous silica containing 3-chloropropyl groups prepared by a direct synthetic approach involving hydrolysis and co-condensation of tetraethylorthosilicate (TEOS) and 3-chloropropyltrimethoxysilane in the presence of the triblock copolymer P123 as template under acidic conditions. Characterization of the functionalized materials by X-ray dif...
Dehydration of aqueous aprotic solvent mixtures by pervaporation Sarıalp, Gökhan; Kalıpçılar, Halil; Yılmaz, Levent; Department of Chemical Engineering (2012) Aprotic solvents are organic solvents which do not easily react with a substance dissolved in it and they do not exchange protons despite of their high ion and polar group dissolving power. Therefore, this characteristic property makes aprotic solvents very suitable intermediates in many industries producing pharmaceuticals, textile auxiliaries, plasticizers, stabilizers, adhesives and ink. Dehydration of these mixtures and recirculation of valuable materials are substantial issues in industrial application...
VAPOR-LIQUID-EQUILIBRIUM OF POLYMER-SOLUTIONS USING A CUBIC EQUATION OF STATE ORBEY, N; SANDLER, SI (1994-07-01) A recently proposed mixing rule has been combined with a cubic equation of state to correlate the vapor-liquid equilibria of various polymer + solvent and solvent + long chain hydrocarbon mixtures. We find that the two-parameter version of this model can correlate the solvent partial pressure in concentrated polymer solutions with high accuracy over a range of temperatures and pressures with temperature-independent parameters. For the solvent + long chain hydrocarbon systems, for which accurate vapor-phase ...
