Synthesis of 5,6-substituted benzimidazoles and their evaluation as potential intermediates in the anaerobic vitamin B12 biosynthesis pathway
We report a modular 3-step synthesis of two benzimidazoles which are putative vitamin B12 biosynthesis intermediates. We also demonstrate their role in producing functional cobamide cofactors and as substrates for the phosphoribosyltransferase CobT.
Nitroso-azomethine(ene) reaction enabled annulations of nitrosoarenes, azomethines and alkenes
An unprecedented example of a nitroso-azomethine(ene) reaction, where azomethine acts as ene-component, mediated annulation of nitrosoarenes, azomethines, and alkenes to arylquinolines is reported.
Prevention of ion migration in lead halide perovskites upon plugging the anion vacancies with PbSe islands
Decorating CsPbX3 nanocrystals with PbSe islands plugs halide vacancies inhibiting anion migration.
Mechanistic variances in NO release: ortho vs. meta isomers of nitrophenol and nitroaniline
A switch in the NO release mechanism is influenced by the hydrogen bonding ability of the substituent.
Structure prediction from spectra amidst dynamical heterogeneity in melanin
Machine learning inverse design of electronic absorption spectra to molecular structures of DHICA melanin.
Insights into interfacial mechanisms: CsPbBr3 nanocrystals as sustainable photocatalysts for primary amine oxidation
This study highlights CsPbBr3 nanocrystals as a potent photocatalyst for oxidative coupling of primary amines to imines, where interfacial interactions markedly impact the reaction yield.
An esterase-cleavable persulfide donor with no electrophilic byproducts and a fluorescence reporter
Hydrogen sulfide (H2S) and associated sulfur species known as persulfide or sulfane sulfur are considered among the first responders to oxidative stress.
Visible light-mediated C (sp3)–H bond functionalization inside an all-organic nanocavity
A new metal-free sp3 C–H bond functionalization in supramolecular confinement is reported that uses visible light to photo-generate C-centered neutral radicals which undergo controlled aerial oxidation in ambient conditions.
About this collection
Kaleidoscope: A discussion meeting in chemistry is an annual gathering of Indian investigators working in various fields of in chemistry and allied areas. Started in 2014, this meeting is a platform for young investigators to discuss on contemporary research trends in chemistry and allied areas to identify and seek suggestions and collaborations among the peer group. The primary aim of this meeting is to provide a platform for the exchange of new ideas and fresh perspectives among chemists of all different fields of research.
Guest edited by Professor G. Naresh Patwari (Indian Institute of Technology Bombay), Professor Jyotishman Dasgupta and Professor Vaibhav Prabhudesai (both from Tata Institute of fundamental Research, Mumbai), this special collection highlights the exciting research by the speakers of Kaleidoscope-2023, the invite only meeting held from 06th to 09th July 2023 at YAAN Wellness Retreat, Udaipur, India. We hope you enjoy reading this collection.
