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 ...

Regioselective Aldol Reactions Directed by Charge and Orbital Effects in Cyclic Germyl Dienolates: Synthesis of Three Distinct Regio‐ and Stereoisomers

Chemistry – A European Journal, EarlyView.
Charge and orbital control represent fundamental principles in organic chemistry. In this study, these principles are applied to the aldol reactions of a cyclic Ge‐dienolate. By systematically tuning the charge and orbital distributions of the Ge‐dienolates and their aldehyde reaction partners, regio‐ and stereoselective access to three distinct aldol ...

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

EFFECTS OF INCREASING PANAMA CANAL TOLL RATES ON U.S. GRAIN EXPORTS [PDF]

Some believe Panama Canal toll rates will increase dramatically as Panama's sovereignty over the Canal becomes complete at the end of this century. This paper focuses on the ability of Panama Canal management to extract additional toll revenues from ...

One century of teaching, research, and innovation in chemical engineering in Mexico: The role of chemical engineering in the background and future of polymer science and industrial production in Mexico

The Canadian Journal of Chemical Engineering, EarlyView.
Timeline of key academic milestones and individuals that shaped chemical engineering at FQ‐UNAM and in Mexico. Abstract One hundred years after the beginning of the teaching of Chemical Engineering in Mexico, which started in 1925 in the former National School of Chemical Sciences, currently Faculty of Chemistry (FQ) at National Autonomous University ...

Governance Drivers of Fossil Fuel Divestment: Evidence From Global Banks

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Climate change poses increasing transition risks for the banking sector, as financial institutions remain exposed to fossil fuel activities despite growing sustainability commitments. This study examines whether corporate governance influences banks' decisions to adopt fossil fuel divestment policies.
