Iridium-catalyzed diacylmethylation of tyrosine and its peptides with sulfoxonium ylides
Pyridyloxy-directed Ir(III)-catalyzed diacylmethylation of protected tyrosines was achieved with alkyl and (hetero)aryl sulfoxonium ylides, furnishing tyrosine-based unnatural amino acids in good yields.
Direct C–H alkylation of 3,4-dihydroquinoxaline-2-ones with N-(acyloxy)phthalimides via radical–radical cross coupling
An organophotoredox-catalyzed direct Csp3–H alkylation of 3,4-dihydroquinoxalin-2-ones employing N-(acyloxy)phthalimides to provide corresponding products in good yields is described.
Iridium(III)-catalyzed photoredox cross-coupling of alkyl bromides with trialkyl amines: access to α-alkylated aldehydes
A C(sp3)–C(sp3) cross coupling approach based on an iridium-photocatalytic radical process has been developed for the synthesis of α-alkylated aldehydes from alkyl bromides and trialkyl amines.
Facet-specific ligand dynamics: scaling the descriptors of Cs2AgBiBr6 nanocrystals
Facet control facilitated by primary amines can enhance the optoelectronic characteristics of A2BIB′IIIX6 perovskite nanocrystals, particularly those with large indirect bandgaps.
Iron-catalyzed cascade C–C/C–O bond formation of 2,4-dienals with donor–acceptor cyclopropanes: access to functionalized hexahydrocyclopentapyrans
Iron-catalyzed stereospecific cascade C–C and C–O bond formation of 2,4-dienals with D–A cyclopropanes has been developed to furnish functionalized cyclopentapyran derivatives.
About this collection
2024 marks the 25th anniversary of the Chemical Research Society of India (CRSI) and the 60th Anniversary of ChemComm. The Chemical Research Society of India (CRSI) has been recognizing, promoting and fostering talent in Chemistry and Chemical Sciences in India over these years. Every year, CRSI recognizes Indian researchers who have contributed significantly to chemical sciences and have instituted Bronze, Silver, and Gold medals since 1999. It is a moment of pride and reflection that Chem Comm has partnered with CRSI to bring an annual collection of exciting research articles by the CRSI Medal Winners every year.
This special collection showcases the recent research carried out by some of the 2024 CRSI medal winners and special lectureship awardees. Please join us in celebrating their success!
