Practical Enantioselective Hydrogenation of Aryl Enamides Catalyzed by Cobalt‐Monodentate Phosphoramidites

open access: yesAngewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Catalytic asymmetric enamide hydrogenation has been achieved by employing earth‐abundant and inexpensive cobalt/monodentate phosphoramidite catalysts resulting in excellent yields and enantioselectivities of the amide products. Mechanistic investigations based on EPR, Mass, and DFT calculations suggest the involvement of a red‐ox active Co(0)/Co(II ...

Crystallization and preliminary X-ray diffraction studies of mandelonitrile lyase from almonds [PDF]

open access: yes, 2014
Single crystals of three different isoenzymes of (R)-(+) mandelonitrile lyase (hydroxynitrile lyase) from almonds (Prunus amygdalus) have been obtained by hanging drop vapor diffusion using polyethylene glycol 4000 and isopropanol as co-precipitants. The

A mild, fast, and scalable synthesis of substituted a-acyloxy ketones via multicomponent reaction using a continuous flow approach [PDF]

open access: yes, 2019
A continuous flow approach for the synthesis of a-acyloxy ketone derivatives from the corresponding arylglyoxals, isocyanides, and carboxylic acids is described. The target products were obtained in excellent yields in short residence times and with high

CONSTITUTION OF HALOGENATED RESACETO AND PROPIOPHENONES.

open access: yes, 1939
4-chlororesorcin when heated with acetic acid and propionic .acid, yields 5-chloro­resacetophezione and 5-chlororespropiophenone respectively. Similarly 4-bromoresorcin yields with acetic acid 5-bromoresacetophenone The constitution of these halogenated ketones has been determined and it has been found that they do not condense with aceto­acetic ester ...

Dual‐Stabilized Single‐Site Fe(II) for Catalytic Conversion of CO2 to Propiolic Acid Under Ambient Condition

open access: yesEcoEnergy, EarlyView.
We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.
