DOI: 10.1021/acs.orglett.5c01106

Abstract: The first iridium-catalyzed intramolecular alkene/alkyne cross-coupling reaction has been developed to prepare a wide range of 12- to 26-membered macrocyclic 1,3-dienes. This operationally simple protocol proceeded by NHTs amide-enabled alkenyl C-H functionalization and exhibited wide… read more here.

Published in 2023 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.3c01611

Abstract: Covalent crosslinking of DNA strands provides a useful tool for medical, biochemical, and DNA nanotechnology applications. Here we present a light-induced interstrand DNA crosslinking reaction using the modified nucleoside 5-phenylethynyl-2'-deoxyuridine (PhedU). The crosslinking ability of… read more here.

Published in 2023 at "Chemical Science"

DOI: 10.1039/d3sc01254a

Abstract: Cationic cyclopentadienyl Ru(II) catalysts can efficiently promote mild intermolecular alkyne-alkene couplings in aqueous media, even in the presence of different biomolecular components, and in complex media like DMEM. The method... read more here.
