Three-Step Synthesis of N-(7-chloro-4-morpholinoquinolin-2-yl)benzamide from 4,7-Dichloroquinoline
MolbankThe quinoline derivative, N-(7-chloro-4-morpholinoquinolin-2-yl)benzamide, was synthesized in a conventional three-step procedure from 4,7-dichloroquinoline using a N-oxidation reaction/C2-amide formation reaction/C4 SNAr reaction sequence. The structure

Knockdown of zebrafish YY1a can downregulate the phosphatidylserine (PS) receptor expression, leading to induce the abnormal brain and heart development [PDF]
, 2016 BACKGROUND: Yin Yang 1 (YY1) is a ubiquitously expressed GLI-Kruppel zinc finger-containing transcriptional regulator. YY1 plays a fundamental role in normal biologic processes such as embryogenesis, differentiation, and cellular proliferation.

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 ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Estimating Half-Lives for Pesticide Dissipation from Plants [PDF]
, 2014 Pesticide risk and impact assessment models critically rely on and are sensitive to information describing dissipation from plants. Despite recent progress, experimental data are not available for all relevant pesticide–plant combinations, and currently ...

European Journal of Organic Chemistry, EarlyView.Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

Zeitschrift für Naturforschung B, 1971 Cyclodehydrohalogenation-beta-Lactams-Morpholin-3-ones-H'-NMR Spectroscopy N-Aryl-N-chloroacetyl-2-chlorophenacylamines (2) give morpholinones 3, or beta-lactams 4, depending upon the N-aryl-substituent. N-Phenyl-N- (2,3-dibromo-3-phenylpropionyl) -4-nitrophenacylamine did not undergo base-catalysed cyclization but gave, instead, the α,β-

Electrophilic Iodination of Heterocyclic Compounds. Recent Advances 2008–2025: Part II
European Journal of Organic Chemistry, EarlyView.Electrophilic iodination using molecular iodine and iodide sources represents an efficient approach for accessing valuable iodinated organic compounds. This review highlights recent advances in the iodination of heterocyclic compounds from 2008 to 2025, emphasizing the role of heteroaryl iodides as important synthetic intermediates for biologically ...

Zeitschrift für Naturforschung B, 1970 The new route to the synthesis of 3-oxo-1,4-oxazines 1 has been extended. N-aryl-N-chloroacetyl-m-nitro-phenacyl amines afford either only oxazine, or beta-lactam or both depending on the nature of the N-aryl substituent. A set of rules indicates from which precursors beta-lactam, as against morpholine formation, may be expected.

Modular synthesis and transition metal-free alkynylation/alkenylation of Castagnoli–Cushmanderived N,O- and N,S-heterocyclic vinyl chlorides [PDF]
, 2020 A modular and functional group-tolerant protocol for the transition metal-free coupling of novel N,O- and N,S-heterocyclic vinyl chlorides with terminal acetylenes and styrenes has been developed, leading to the epimerization-free synthesis of fully ...
