Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.

[3+2] Annulation of Donor–Acceptor Cyclopropanes with Vinyl Azides

open access: yes, 2017
A Sc(OTf)3-catalyzed reaction of vinyl azides with donor–acceptor cyclopropanes affords highly functionalized azidocyclopentanes in a diastereoselective fashion. The resulting azidocyclopentanes could be transformed into various cyclic scaffolds.MOE (Min.

Adverse Effects of Unsaturated Organic Compounds on Kinetic States During Locomotion Uncovered by Comprehensive Analysis of Behavioral Toxicities in C. elegans

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Organisms in human living spaces are surrounded by a variety of engineered substances. These chemical compounds have unexpected effects on the environment and human health. In particular, workers in industries face the risk of a health hazard caused by high‐dose or long‐term exposure to chemicals in the workplace.

Recent Advances in Cryogel Applications for Musculoskeletal Regeneration

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Fragmentation of carbohydrate anomeric alkoxyl radicals. A new synthesis of chiral ß-iodo azides, vinyl azides and 2H-azirines

open access: yes, 2003
The reaction of 3-azido-2,3-dideoxy-hexopyranose compounds from the D-gluco, D-galacto, D-lacto, and L-arabino carbohydrate series, with (diacetoxyiodo)benzene and iodine, generated 2-azido-1,2-dideoxy-1-iodo-alditols with one carbon less than the ...
