Asymmetric Synthesis with Hypervalent Iodine Reagents.
This chapter describes recent developments in stereoselective synthesis using hypervalent iodine reagents.
متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
متن کاملAsymmetric Synthesis Using Organometallic Reagents and Optically Pure Vinylic Sulfoxides
A new, general method is developed for preparation of various 3-substituted carbonyl compounds of very high optical purity. Application of this method is made to asymmetric synthesis of either enantiomer of 3—methylalkanoic acids, of optically pure 3-methylcyclopentanone, 3—methylcyclohexanone, 3-naphthylcyclopentanone and 3-vinylcyclopentanone j. 9,11-Seco steroid and steroid intermediate are ...
متن کاملCoordinating anions: (phosphino)tetraphenylborate ligands as new reagents for synthesis.
Anionic, electron-releasing phosphines that incorporate a borate counteranion within the ligand framework are promising reagents for organometallic catalysis. This report describes the synthesis of a new class of monodentate tertiary phosphines built upon the commonly employed tetraphenylborate anion. These new phosphines are highly stable and strongly electron-releasing and readily coordinate ...
متن کاملPolyborylated reagents for modern organic synthesis
Diverse kinds of gem- and vic-diborylated compounds are now readily available thanks to advances in gem-diborylation of lithium carbenoids as well as vic-diborylation of carbon-carbon multiple bonds with diboron compounds. These diborylated reagents lead to invention of polyborylated reagents and many novel and useful synthetic methods for supreme stereocontrol. This review summarizes preparati...
