Core-substituted naphthalene diimides: influence of substituent conformation on strong visible absorption [PDF]

, 2017
Substitution of the aromatic core of naphthalene diimide (NDI) chromophores by morpholine leads to molecules with strong absorbance in the visible spectrum.

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.

Synthesis of Thiazole Derivatives as Antimicrobial Agents by Green Chemistry Techniques

Journal of the Turkish Chemical Society, Section A: Chemistry, 2018
Amine (2) and (26) was obtained from the condensation of the corresponding amines with 3,4-difluoronitrobenzene. The reduction of nitro group produced the corresponding amines (3 and 27).

Perfluoroalkylated amphiphiles with a morpholinophosphate or a dimorpholinophosphate polar head group [PDF]

, 1998
Some previously synthesized (perfluoroalkyl)alkyldimorpholinophosphates, CnF2n+1CmH2mOP(O)-[N(CH2CH2)(2)O](2), were found remarkably to stabilize heat sterilizable water-in-fluorocarbon reverse emulsions and to have a strong proclivity to self-aggregate ...

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

Macromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

1,2-Dimorpholinoethane-1,2-dithione

Acta Crystallographica Section E, 2009
The title compound, C10H16N2O2S2, was prepared by a reaction of 4-tert-butylbenzene, morpholine and sulfur. In the crystal structure, both morpholine rings display the typical chair conformation.

Crystal structure and theoretical study of (2E)-1-[4-hydroxy-3-(morpholin-4-ylmethyl)phenyl]-3-(thiophen-2-yl)prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2018
In the title compound, C18H19NO3S, the morpholine ring adopts a chair conformation. The thiophene ring forms dihedral angles of 26.04 (9) and 74.07 (10)° with the benzene ring and the mean plane of the morpholine ring, respectively.

Synthesis of (R) and (S)-3-Chloro-5-(3-methylmorpholino)-4H-1,2,6-thiadiazin-4-ones

Molbank, 2020
Reaction of 3,5-dichloro-4H-1,2,6-thiadiazin-4-one with (R) and (S)-3-methylmorpholines (2 equiv), in THF, at ca. 20 °C gave (R) and (S)-3-chloro-5-(3-methylmorpholino)-4H-1,2,6-thiadiazin-4-ones in 95 and 97% yields, respectively. The new compounds were

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

Macromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione

Molbank, 2012
3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione was obtained in good yields (72–82%) by nucleophilic substitution of 3-chloro-4-(1<em>H</em>-indol-3-yl)cyclobut-3-ene-1,2-dione with morpholine.
