Chiral Auxiliaries in Asymmetric Synthesis

Background The use of chiral auxiliaries in the synthesis of enantiomerically pure compounds has found wide application for a variety of reactions over the last three decades. Despite the extensive developments in this area by many academic and industrial research groups, new auxiliary controlled reactions continue to evolve frequently [1]. First objectives in this area have been to develop chi...

NOVEL 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...

Highly potent chiral labeling reagents for the discrimination of chiral alcohols.

Highly sensitive chiral labeling reagents, (1R,2R)- and (1S,2S)-2-(2,3-anthracenedicarboximido)cyclohexanecarboxylic acids [(1R,2R)- and (1S,2S)-A] and (1R,2R)- and (1S,2S)-2-(2,3-naphthalenedicarboximido)cyclohexanecarboxylic acids [(1R,2R)- and (1S,2S)-A'], were prepared. Reagent A has enabled us to discriminate the enantiomers of anteiso fatty alcohols up to C9 methyl branching by 1H NMR, an...

Asymmetric 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 ...
