Asymmetric synthesis of threonine and allo-threonine via stereochemically inert dissymmetric complexes of cobalt(III)
Abstract
The glycine fragments of the optically active cobalt(III) complexes (Ia and b), and (IIIa and b) condense with acetaldehyde in water at pH 11, and decomposition of the resulting complexes gives a mixture of asymmetric theorine and allo-threonine
