Solid-Phase Conversion of Four Stereoisomers into a Single Enantiomer

Viedma ripening is an emerging method for the solid-phase deracemization of mixtures of enantiomers. Up to now, the scope of the method has remained limited to molecules with a single stereocenter. We show here that this method can be extended to obtain a single enantiomer from a mixture of stereoisomers with two different stereocenters. In addition, we show that by using tailor-made chiral additives, the conversion time can be reduced by a factor of 100.

Synthesis in a stage of N-methoxyindolinones, N-methoxymaleimides and maleic anhydrides starting from α-halogen hydroxamic acids

α-Halo hydroxamic acids were used in the synthesis of N-methoxyindolinones, symmetric and dissymmetric N-methoxymaleimides in good yields. The hydrolysis of N-methoxymaleimides constitues a new and good route to maleic anhydrides.

SYNTHESE DE N-AMINO MALEIMIDES ET D'ANHYDRIDES MALEIQUES DISUBSTITUES A PARTIR D'α-HALOGENO HYDRAZIDES. ETUDE DU MECANISME DE LA REACTION.

α-Halohydrazides react with 2-aminopyridine to give symmetrically substituted N-aminomaleimides.We have shown that this reaction proceeds through the formation of 4-hydroxyimidazopyridines.This result opens a new route to dissymetrically substituted N-aminomaleimides.The hydrolysis of N-aminomaleimides is a grood route to substituted maleic anhydrides.
