Synthesis and late-stage functionalization of complex molecules through C-H fluorination and nucleophilic aromatic substitution. [PDF]

open access: yes, 2014
We report the late-stage functionalization of multisubstituted pyridines and diazines at the position α to nitrogen. By this process, a series of functional groups and substituents bound to the ring through nitrogen, oxygen, sulfur, or carbon are ...

Sulfur Ylides in Skeletal‐Editing—Ring Expansion Reactions

open access: yesHelvetica Chimica Acta, Volume 109, Issue 3, March 2026.
Sulfur ylides (S‐ylides) are emergent diazo surrogates that enable skeletal editing and ring expansion with safer handling and broad functional group tolerance. This perspective covers pioneer works and highlights recent advances in the field, while outlining key challenges and future directions that may redefine the role of S‐ylides in modern ...

Structure and activity relationships for amine-based CO2 absorbents-II [PDF]

open access: yes, 2009
A study to determine the structure and activity relationships of various amine-based CO2 absorbents was performed, in which the absorption of pure CO2 at atmospheric pressure was measured to assess the total absorption rates and capacities.

Some Like It Hot, Some Like It Warm: Phenotyping To Explore Thermotolerance Diversity [PDF]

open access: yes, 2012
Plants have evolved overlapping but distinct cellular responses to different aspects of high temperature stress. These responses include basal thermotolerance, short- and long-term acquired thermotolerance, and thermotolerance to moderately high ...

A Facile Protocol for C(sp2)–C(sp3) Bond Formation Reactions Toward Functionalized E3 Ligase Ligands

open access: yesChemMedChem, Volume 21, Issue 4, 25 February 2026.
A robust C(sp2)–C(sp3) decarboxylative coupling strategy enables access to new CRBN ligands and degraders with improved physicochemical properties. This synthetic approach is expanding the chemical space beyond C(sp2)–N linkages, fine‐tuning proteolysis‐targeting chimera activities and unlocking previously inaccessible degrader chemotypes.

Okaramine insecticidal alkaloids show similar activity on both exon 3c and exon 3b variants of glutamate-gated chloride channels of the larval silkworm, Bombyx mori [PDF]

open access: yes, 2017
The okaramine indole alkaloids were recently shown to be more selective than ivermectin in activating the glutamate-gated chloride channels of the silkworm larvae of Bombyx mori (BmGluCls).

Synthesis of Substituted Cyclic Amines From Protected Amino Acids Using Oxidative Decarboxylation and Alkylation

open access: yesAsian Journal of Organic Chemistry, Volume 15, Issue 2, February 2026.
Simple access to alkylated 3D scaffold via oxidative radical decarboxylation, trapping of iminium, and successive reaction with organometallic reagent in the presence of BF3 . ABSTRACT Cyclic amines are vital scaffolds in bioactive molecules and drug discovery, often functionalized via electrochemical Shono‐type oxidation to access N‐acyliminium ...
