Synthesis of 6H-pyrrolo[3?,4?:2,3][1,4]diazepino[6,7,1-hi]indole-8,10(7H,9H)-dion es using 3-bromo-4-(indol-1-yl)maleimide scaffold

Series of 3-arylalkyl- or 3-alkylamino-4-(indol-l-yl)maleimides and bis(indol-l-yl)maleimides were synthesised. The cyclization of the 3-substituted 4-(indol-l-yl)maleimides under the action of acids resulted in the formation of diazepine[1,4] derivatives with indoline and maleimide nuclei annelated. These compounds readily produced the corresponding indolomaleimidodiazepines[1,4] after dehydrogenation.

Comparative analyses of a family of potential self-replicators: The subtle interplay between molecular structure and the efficacy of self-replication

It is envisioned that protocols based on self-replication will emerge as a formidable synthetic apparatus for the production of nanoscale assemblies through molecular structures that are capable of automultiplication with high reaction rates and selectivities. To achieve this goal, a complete understanding of the relationship between molecular structure and repli cation efficiency is necessary. Rigorous experimental and theoretical analyses of a series of self-complementary scaffolds that are intimately related in a constitutional sense, manufactured through the Diels-Alder reaction of complementary subunits, were undertaken. Experimental and computational methods were employed to map the key determinants that dictate the emergence of self-replicative function, as well as the efficiency, rate and selectivity of the self-replicative processes.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.25021-08-3. In my other articles, you can also check out more blogs about 25021-08-3

Design of Redox/Radical Sensing Molecules via Nitrile Imine-Mediated Tetrazole-ene Cycloaddition (NITEC)

The current study introduces a novel synthetic avenue for the preparation of profluorescent nitroxides via nitrile imine-mediated tetrazole-ene cycloaddition (NITEC). The photoinduced cycloaddition was performed under metal-free, mild conditions allowing the preparation of a library of the nitroxide functionalized pyrazolines and corresponding methoxyamines. High reaction rates and full conversion were observed, with the presence of the nitroxide having no significant impact on the cycloaddition performance. The formed products were investigated with respect to their photophysical properties in order to quantify their “switch on/off” behavior. The fluorescence quenching performance is strongly dependent on the distance between the chromophore and the free radical spin as demonstrated theoretically and experimentally. Highest levels of fluorescence quenching were achieved for pyrazolines with the nitroxide directly fused to the chromophore. Importantly, the pyrazoline profluorescent nitroxides were shown to efficiently act as sensors for redox/radical processes.

Synthesis and characterisation of peripherally functionalised dendritic molecules

A number of peripherally functionalised dendritic molecules were synthesised in almost quantitative yield by a synthetic method involving the reaction between amines and isocyanates. The peripheral functional groups were incorporated by preparing a number of branched subunits, based on tris(hydroxymethyl)aminomethane (TRIS), 1, possessing three nitro, methoxy, methyl or maleimide terminal functionalities. Attachment of these branched units to the core molecules 4,4?-methylenebis(phenyl isocyanate) 13 and 1,3,5-benzene triisocyanate 20 afforded the corresponding dendritic molecules possessing 6 or 9 peripheral functional groups. Functional group conversions on the dendritic molecules have been successfully carried out, including hydrogenation of the terminal nitro to the corresponding amine and cleavage of the methoxy ether to give the corresponding phenol.
