The biocatalytic oxidative tandem decarboxylation of C7–C18 dicarboxylic acids to terminal C5–C16 dienes was catalyzed by the P450 monooxygenase OleT with conversions up to 29 % for 1,11-dodecadiene (0.49 g L–1). The sequential nature of the cascade was proven by the fact that decarboxylation of intermediate C6–C11 ω-alkenoic acids and heptanedioic acid exclusively gave nonconjugated 1,4-pentadiene;
C7-C18 二元羧酸到末端 C5-C16 二烯的生物催化氧化串联脱羧由 P450 单加氧酶 OleT 催化,1,11-十二二烯(0.49 g L-1)的转化率高达 29%。中间体 C6-C11 ω-链烯酸和庚二酸的脱羧反应仅生成非共轭 1,4-戊二烯,证明了级联的顺序性质;放大允许分离 1,15-十六二烯和 1,11-十二二烯;该系统代表了一条从可再生二元羧酸获得末端二烯的绿色短途路线。
