“…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).…”
