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 spirocyclic cyclopentapyrans by the Pauson-Khand reaction on camphor tethered enynes
Sezer, Serdar; Gumrukcu, Yasemin; ŞAHİN, Ertan; Tanyeli, Cihangir (2008-12-01)
An intramolecular Pauson-Khand reaction of camphor tethered enynes derived from homoallyl, homomethallyl and homopropargyl alcohols is described. Homoallyl, homomethallyl, and homopropargyl moieties are easily constructed on the camphor carbonyl group with excellent diastereoselectivity due to endo-face selectivity, and with known stereochemistry. Each enantiomerically pure enyne affords the conformationally most stable diastereomeric spirocyclic cyclopenta[c]pyran ring system.
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...
