Abstract:In this manuscript we report the synthesis of 3‐amido‐benzo[b]silines thanks to a 2‐step strategy involving a 3‐component silylformylation of ynamides followed by a Friedel‐Crafts cyclization/ isomerizing dehydration domino sequence. This reaction is tolerant to various structural variations and has allowed us to synthesize a library of diversely substituted silacycles with yields from 28 to 85%. We also studied the fluorescence properties of these compounds which show structural similarities with recognized p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
