The interesting bronchodilator activity of l-11-deoxy-11 alpha-[(2-hydroxyethyl)thio]prostaglandin E2 methyl ester (3a) is described. The preparation of 3a and its analogues by Michael-type additions to various members of the PGA series or by total synthesis using the lithiocuprate conjugate addition process is also described. Structure-activity relationships in this series are discussed.
Das Anion (II) kann aus 9H‐Pyrrolo(1,2‐a)indol (I) mit Alkyllithiumverbindungen hergestellt werden und wird mit Chloralkyläthern zu (IIIa) und (IIIb) umgesetzt.
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.
