A method is presented for the high‐yield synthesis of Fmoc amino acids, which precludes racemization and over‐reaction due to carboxyl activation. A detailed procedure is given for the preparation of Fmoc‐ONSu.
Die Pyrrolidino‐ und Piperidino‐Aromaten (I) werden mit Trifluoracetanhydrid in o‐Stellung zu (II) und z.Tl. seinen Hydraten (III) umgesetzt und dann thermisch über diskutierte Zwischenstufen zu (IV) cyclisiert.
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.
