Organocatalyst Efficiency in the α‐Aminoxylation and α‐Hydrazination of Carbonyl Derivatives in Aqueous Media or in a Ball‐Mill

European Journal of Organic Chemistry (2016)

Eva Veverková Viktória Modrocká Radovan Šebesta

Pyrrolidine‐derived organocatalysts have been tested in two types of α‐heterofunctionalization reactions in aqueous media or under solvent‐free ball‐milling conditions. The best results in terms of both activity and enantioselectivity were obtained with O ‐silylated 4‐hydroxyproline derivatives in the α‐aminoxylation reaction between n ‐butyraldehyde and nitrosobenzene (83 % yield in water, 86 % yield by ball milling and ee > 99 %). A very good yield (82 %) and excellent optical purity ( ee > 99 %) were also achieved in the α‐hydrazination reaction of 3‐phenylpropanal with dibenzyl azodicarboxylate by the ball‐milling technique.

Microwave-Assisted Method for Synthesis of 1,3-Disubstituted Pyrroles

Synthetic Communications (2009)

Viera Poláčková Eva Veverková Štefan Tomá Dariusz Bogdał

Abstract 1,3-Disubstituted pyrroles were prepared by a microwave-assisted reaction of pyrrolidine and aldehydes in toluene as well as in solvent-free conditions. Reactions were completed in a few minutes in the solvent-free condition but a long time (up to 30 min) was necessary to complete reactions in toluene. Yields of products depended considerably on the aldehyde used.
