Preparation of 3?azetidinols with non?bulky 1?alkyl substituents

, 1987
Cyclization of either the tetrahydropyranyl or trimethylsilyl ether of 1?(alkylamino)?3?chloro?2?propanols 1 followed by cleavage of the azetidinyl ether provides a general method for the preparation of 1?alkyl?3?azetidinols.

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

Post‐Modification of Tripyrenylenes to Enantiopure π‐Extended D3‐Symmetric Propellers

Chemistry – A European Journal, EarlyView.
The post‐modification of tripyrenylenes to π‐extended enantiopure propellers with tris‐phenanthrophenazines is presented and the chiroptical properties as well as the solid‐state packings investigated in comparison to the corresponding racemic mixtures.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...
