摘要:The present invention relates to a process for the preparation of enantiomerically enriched cyclobutylamines of formula (I) from α-tertiary cyclobutanones and reacting said enantiomerically enriched cyclobutylamines to enantiomerically enriched cyclobutylamides. Such compounds are useful intermediates in the synthesis of microbiocidal thiazole compounds.

摘要:A method and a biomaterial for the total biosynthesis of a key paclitaxel precursor substance baccatin III, and the use. The biological enzyme composition used in the method comprises taxane 9α-hydroxylase (T9αH) and taxane C4-C20 oxetane-forming enzyme (TOT). The core ingredients of the biosynthetic pathway of baccatin III are identified, and an artificial synthesis route for baccatin III is constructed, which pave the way for the efficient development of a green and low-carbon production pathway for taxane products such as paclitaxel by means of synthetic biology.

摘要:Transgenic plants, plant material, and plant cells for synthesis of polyhydroxyalkanoates, preferably poly(3-hydroxybutyrate) (also referred to a as PHB) are provided. Preferred plants that can be genetically engineered to produce PHB include plants that do not normally produce storage products such as oils and carbohydrates, and plants that have a C 4 NAD-malic enzyme photosynthetic pathway. Such plants also advantageously produce lignocellulosic biomass that can be converted into biofuels. An exemplary plant that can be genetically engineered to produce PHB and produce lignocellulosic biomass is switchgrass, Panicum virgatum L. A preferred cultivar of switchgrass is Alamo. Other suitable cultivars of switchgrass include but are not limited to Blackwell, Kanlow, Nebraska 28, Pathfinder, Cave-in-Rock, Shelter and Trailblazer.
