Abstract:Läßt man das Chlorid des Bernsteinsäuremethylesters (II) in Gegenwart von Aluminiumchlorid in Benzol (III) auf 4,5,6,7‐Tetrahydrobenzo(b)thiophen‐4‐on (Ia) oder 5,6,7,8‐Tetrahydro‐4H‐cyclohepta(b)thiophen‐4‐on (Ib) einwirken, so entstehen als Hauptprodukte die 3‐Phenyl‐Verbindungen (IV), die mit Lithium‐aluminiumhydrid zu den Thiophenen (Va) und (Vb) reduziert werden können.
“…In the approach of Fabrichnyi and co-workers (1965), the lactam 206 is transformed into 187 via a sequence similar to the one previously discussed (Scheme ) . The lactam originates from a Beckmann rearrangement sequence performed on ketone 205 .…”

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.
