Stereoregular polymerization of propylene oxide by bis-dimethylaluminium oxide
Oktem, Z; Alyuruk, K (1998-02-01)
Stereoregular polymerization of propylene oxide (PO) by bis-dimethylaluminum oxide (BMAO) was studied. It is found that at 80 degrees C a relatively high initial rate of the process rapidly dies away. Hy measuring and identifying the evolved by-product gases of the polymerization it was concluded that the decay of the rate is due to the transfer of a proton from the methyl (Me) group of PO, to the Me-Al groups of BMAO, by forming an aluminium allylalkoxide bond and a methane molecule. However, this transfor...

Stereoselective oxidation of sulfides to sulfoxides by n-chloramines
İpek, Halil; Akdağ, Akın; Department of Chemistry (2014)
Chiral sulfoxides are present in many biologically active compounds. Asymmetric synthesis of the sulfoxides has been performed by chiral metal complexes and chiral peroxides. Although the asymmetric organooxidation of sulfides by chiral peroxides proved to be successful, peroxides are difficult to handle and obtain. In this study, a new metal free method has been developed to oxidize sulfides to chiral sulfoxides with easily accessible chiral N-chloramines. For this purpose, chiral reagents were synthesized...
Stereoselective synthesis of optically active cyclopenta[c]pyrans and cyclopenta[c]furans by the intramolecular Pauson-Khand reaction
Sezer, Serdar; ŞAHİN, Ertan; Tanyeli, Cihangir (Elsevier BV, 2010-03-16)
An intramolecular Pauson-Khand reaction of enynes derived from homoallyl, homopropargyl, and allyl alcohols is described. 2-Heteroaryl-substituted homoallyl, homopropargyl, and allyl alcohols are easily and efficiently resolved through enzymatic resolution in high ee (91-99%) and with a known stereochemistry. Each enantiomerically enriched enyne derived from homoallyl and homopropargyl alcohols affords the conformationally most stable diastereomeric cyclopenta[c]pyran ring system as the sole product, wherea...
