Enzymatic kinetic resolution of primary allenic alcohols. Application to the total synthesis and stereochemical assignment of striatisporolide A

Abstract: Crude Porcine pancreatic lipase was successfully used for the kinetic resolution of axially chiral primary allenic alcohols providing very high enantioselectivities with E values above 200. This simple access to optically active allenes was applied to the total synthesis of the fungal metabolite (-)-striatisporolide A, allowing its unambiguous stereochemical assignment.

“…The use of FMN-dependant oxidoreductases for the oxidation of , -unsaturated carbonyl compounds and thioethers to the corresponding epoxides and sulfoxides has been reported (Mueller et al, 2009). Biocatalysis has been used to prepare many novel compounds including (-)-striatisporolide A (Deska & Backvall, 2009) (Sawangwan et al, 2009), febrifugine (Wijdeven et al, 2009) and the four different stereoisomers of aszonalenin (W. B. . The solid phase synthesis of peptides using protease catalysis has been described (Haddoub et al, 2009).…”

“…Auch wenn optisch aktive Allene heutzutage in der Regel durch Umsetzung enantiomerenangereicherter, meist propargylischer Vorstufen unter Erhalt der stereochemischen Information synthetisiert werden, [4] besteht durchaus ein wachsendes Interesse an Ansätzen zur kinetischen Racematspaltung von Allenen. [5,6] In diesem Zusammenhang konnten wir kürzlich Schweinepankreas-Lipase (PPL) als herausragenden Biokatalysator für die kinetische Racematspaltung axial-chiraler primärer Allenole identifizieren. [6] Das rohe Enzympräparat katalysierte dabei die Umesterung in organischen Lçsungsmitteln mit teilweise exzellenter Enantioselektivität.…”

Jedoch bedingt die Enzym-vermittelte Racematspaltung eines 50:50-Gemisches immer auch eine Beschränkung der Ausbeute auf hçchstens 50 % enantiomerenreinen Produktes.…”
