Though the three-dimensional structures of barley alpha-amylase isozymes AMY1 and AMY2 are very similar, they differ remarkably from each other in their affinity for Ca(2+) and when interacting with substrate analogs. A surface site recognizing malto

The novel, diastereomeric meso- (cis) and (±)- (trans) nitroxides 2,5-dicarboxymethyl-2,5-dimethylpyrrolidine-1-oxyl have been synthesized via a dienolate based strategy. Both optically pure enantiomers of the C 2 symmetric trans diastereomer have b

The novel C2 symmetric chiral amine trans-2,6-dimethyl-2,6-diphenylpiperidine has been synthesized via two successive nitrone nucleophilic addition-oxidation sequences, followed by reduction of the intermediate nitroxide. Pure enantiomers have been o

New stable nitroxides, analogous to TEMPO (tetramethylpiperidine-N-oxyl) where two α,α′ methyl groups are formally replaced by ester functions, are prepared via dienolate chemistry followed by a deprotection–oxidation sequence.
