Highly chemoselective addition of Schwartz's reagent to widely available azlactones is described. This method allows the preparation of challenged functionalized α-amino aldehydes, in good to high isolated yields at room temperature, after only 2 min reaction. The presence of sensitive functionalities or electronic factors does not compromise the potential of the method. The use of an excess of the reducing reagent gave a very functionalized allylic alcohol derivative in 86% yield.

4-Substituted oxazolines, which are readily synthesized from naturally occurring α-amino acids, are converted efficiently and stereospecifically to β-amidoaldehydes in the presence of synthesis gas and catalytic dicobalt octacarbonyl.

Asymmetric oxidation of 1,2-diols, aminoalcohols, and aminoaldehydes in the presence of copper(II) triflate and (R,R)-Ph-BOX was accomplished by electrochemical method using Br- as a mediator. This oxidation was applicable to kinetic resolution of racemic cis-cycloalkane-1,2-diols, aminoalcohols, and aminoaldehydes to afford optically active compounds with good to high enantioselectivity.

(Chemical Equation Presented) Selective recognition: The first efficient method for the kinetic resolution of racemic amino aldehydes (see scheme, PG=protecting group) is based on a copper(II)/(R,R)-Ph-BOX complex. The coordinated amino aldehydes were tra
A versatile approach to 3-alkyl and 2,3-dialkylpyrroles

A route is described towards N-Benzoyl-3-Alkyl and N-Benzoyl-2,3-Dialkyl pyrroles from α-Amidoketones via an intramolecular Wittig reaction to afford 4-Phenylthio-3-Pyrrolines which are then oxidised to the corresponding sulphones and aromatised by treatm
