Optisch aktives Phytol

Abstract: Bei der ziemlich schlechten Krystallisationsfahigkeit der meisten Phytolderivate schienen Spaltungsversuche mit naturlichem Phytol nieht sehr aussichtsreieh j zudem hatte der negative Ausfall solcher Versuche die beiden erstgenannten Alternativen, die fur die moglichen Ursachen der optischen Inaktivitat naturlicher Phytolpraparate bestehen, nicht ausschalten konnen. Wir entschlossen uns daher, ein optisch aktives Phytolpraparat durch Synthese aufzubauen.Der Weg, den wir benutzten, geht vom optisch aktiven Citr… Show more

“…The evidence discussed by Abrahamsson, Stallberg-Stenhagen & Stenhagen (1963) relating to the configuration of 3,7,11,15-tetramethylhexadecanoic acid isolated from butterfat by Hansen & Shorland (1953) together with its specific rotation ([a] 18 ' 5°, +1-1 in chloroform) in comparison with that of naturally occurring phytol ([a]}, 80 , + O-2O-O-21 0 ; Karrer, Geiger, Rentschler, Zbinden & Kugler, 1943) is not inconsistent with its biosynthesis from this alcohol.…”
