The present invention relates to the use of hydrocarbons derived from natural gas in the fermentative production of biochemicals including biofuels. More specifically, the present invention provides the method for manufacturing dihydroxyacetone ("DHA") from natural gas, biogas, biomass and CO2 released from industrial plants including electricity-generating plants, steel mills and cement factories and the use of DHA as a source of organic carbon in the fermentative production of biochemicals including biofuels. The present invention comprises three stages. In the first stage of the present invention, syngas and formaldehyde are produced from natural gas, biogas, biomass and CO2 released from industrial plants. In the second stage of the present invention, formaldehyde and syngas are condensed to produce DHA. In the third stage of the present invention, biochemicals including biofuels are produced from DHA using fermentation process involving wild type or genetically modified microbial biocatalysts.
loroxanthin (1) was accomplished by Horner-Wadsworth-Emmons reaction of C25-apocarotenal 8 having a silyl-protected 19-hydroxy moiety with C15-phosphonate 25 bearing a silyl-protected 3-hydroxy-ε-end group. Preparation of apocarotenal 8 was achieved viaStillecouplingreaction of alkenyl iodide 10 with alkenyl stananne 9, whereas phosphonate 25 was prepared through treatment of ally alcohol 23 with
氯黄素 ( 1 )的首次全合成是通过具有甲硅烷基保护的 19-羟基部分的 C 25 -胡萝卜醛8与带有甲硅烷基保护的 3-羟基-ε- 的C 15 -膦酸酯25的 Horner-Wadsworth-Emmons 反应完成的端组。apocarotenal 8的制备是通过烯基碘化物10与烯基锡烷9的Stille 偶联反应实现的,而膦酸酯25是通过烯丙醇23用亚磷酸三乙酯和ZnI 2处理制备的。烯丙醇23衍生自已知的 (3 R,6 R )-3-羟基 C 15 -醛20,其通过使用半制备手性 HPLC 柱直接光学拆分外消旋体20获得。
