“…Sulfur ylides have been known to react with carbonyl compounds to produce epoxides along with regeneration of the sulfide that was used to form sulfur ylides [10]. We designed a catalytic process of sulfur-ylide-mediated epoxidation reaction (Scheme 2) [11], which marked one of the early examples of organocatalytic reactions.…”

“…Recently, a simple, one-pot procedure, utilizing imines, has been developed for the asymmetric synthesis of cis-N-substituted aziridine-2-carboxylic acids via a Darzens-type reaction (equation 154) 559 560 . The reaction also occurs with rhodium acetate and dimethyl sulfide as catalyst 561 . A wide range of oxiranes may be readily prepared using this type of methodology.…”

“…Der gewünschte a-Mercapto-a-allylessigsäureethylester (10) wurde in guten Ausbeuten erhalten (Schema 4).Hier konnten wir zeigen, dass elektronenreiche Eisen-Komplexe wie Bu 4 N[Fe(CO)3 (NO)] (TBAFe), in denen dem Metall formal die Oxidationsstufe ÀII zugeordnet werden kann, effizient Diazoverbindungen für Carbentransferreaktionen vorbereiten. [13f] Mit Blick auf die bislang erhaltenen Ergebnisse nahmen wir nun an, dass der Komplex auch zu einer Sequenz aus Sulfenylierung und Doyle-Kirmse-Reaktion genutzt werden kçnnte.…”
