“…[111] The N-acetyl compound 29 was synthesized from furan in a multistep reaction sequence and then further transformed into pyridoxine by an anodic electrolytic oxidation in methanol followed by a saponification (Scheme 19). [112] However, the overall yield of the process is low and not competitive with other approaches.…”

“…Einen anderen Zugang bildet die Prenol-Prenal-Route, [201,202] die ausgehend von billigem Isobuten (108; C 4 ) und Formaldehyd (C 1 ) zu Citral (64; C 10 ) als Zwischenprodukt führt. Myrcen (107; C 10 ) aus natürlichen Quellen wurde in einem Rhodium-katalysierten Prozess unter Verwendung eines wasserlçslichen Phosphinliganden alkyliert [173,203] und ergab nach Decarboxylierung und nachfolgender Hydrierung Hexahydropseudoionon (112).…”

“…Als nachteilig erwiesen sich allerdings die große Stufenzahl und unzureichende Ausbeuten einzelner Umsetzungen sowie die damit verbundene, recht bescheidene Gesamtausbeute. [112] Allerdings liefert dieser Prozess nur eine geringe Gesamtausbeute und ist damit gegenüber anderen Verfahren nicht konkurrenzfähig. [111] Die N-Acetyl-Verbindung 29 wurde in einer vielstufigen Reaktionssequenz aus Furan synthetisiert.…”

“…Several approaches following this concept were described over many years 111. The N ‐acetyl compound 29 was synthesized from furan in a multistep reaction sequence and then further transformed into pyridoxine by an anodic electrolytic oxidation in methanol followed by a saponification (Scheme ) 112. However, the overall yield of the process is low and not competitive with other approaches.…”
