Graphical Abstract New inorganic–organic hybrid materials effectively and diastereoselectively catalyze the C–C bond formation upon nitroaldol (Henry) reaction. Highlights ► New hybrid materials were easily prepared from zinc(II) salt, sulfuric acid and amines. ► Full structural characterization of the compounds was performed. ► The synthesized compounds act as effective catalysts in the nitroa...

An environmentally-friendly, enzyme-promoted procedure for the Henry reaction was first studied using water-in-[Bmim][PF6] microemulsions as reaction medium. The Amano acylase from Aspergillus oryzae showed better catalytic activity for the addition reactions of nitromethane with a series of aromatic aldehydes, and a highest yield of 90% was obtained.

A catalytic asymmetric nitro-Mannich (aza-Henry) reaction with rare earth metal/alkali metal heterobimetallic catalysts is described. A Yb/K heterobimetallic catalyst assembled by an amide-based ligand promoted the asymmetric nitro-Mannich reaction to afford enantioenriched anti-b-nitroamines in up to 86% ee. Facile reduction of the nitro functionality allowed for efficient access to optically ...

an organosuperbase (n,n-dimethylbiguanide) immobilized on mesoporous and magnetically separable silica supports, was found for the first time, to act as a highly-stable, scalable and efficient heterogeneous catalyst for the henry reaction under mild and neutral condition. several factors such as catalyst amount, solvent and reaction time concerning the reactivity were also discussed. the proced...

Isoxazoline analogues of artemisinin were obtained in low yield and low diastereoselectivity from the 1,3-dipolar cycloaddition of nitrile oxides. Alternatively, starting from the aldehyde 7, a number of transformations--Wittig reaction and reduction, Henry reaction and cyanohydrin formation--were achieved in significantly higher yields. In the cases where a new stereocenter was introduced this...

Here we present a novel dynamic organocatalyst, based on a first-generation molecular motor core, able to control the stereochemical outcome of the Henry reaction using both light and heat as external stimuli.

A bis(thiourea) organocatalyst with a planar chiral [2.2]paracyclophane backbone has been synthesized and applied to the Henry reaction. The obtained high reactivity and enantioselectivity from the reaction of aromatic aldehydes with nitroalkanes suggested the significant potential of [2.2]paracyclophane to serve as the backbone of the organocatalyst.

General and operative domino Claisen-Schmidt/Henry (CS/H) reaction has been revealed to obtain highly substituted chiral decalines in good yields with excellent ees and des by using push-pull enamine catalysis.
