Production produce synthetic intermediates
S has developed a very innovative methodology for the oxidative cleavage of alkenes using polymetallic catalysts, which ensure a very safe and cost-effective production process. This process is being protected by more than five patent families. We now wish to valorize several new synthetic intermediates produced with this technology, as starting materials for the synthesis of a range of derivatives with applications in the fields of active pharmaceutical ingredients, surfactants, emulsifiers, anti-microbials, polymers and coatings. This research will thus focus on using these innovative intermediates as new industrial feedstocks to produce marketable chemicals with high added value.VIDEO ON THE TOPIC: 1.

The combination of biological and chemical approaches for the generation of new and diverse natural products holds much promise.
While mutasynthesis based approaches are still very relevant, more recent approaches have utilised genetic and metabolic engineering to generate key intermediates for chemical syntheses. This new semi-synthetic approach exploits the ability of biological systems to efficiently generate complex chiral molecules and of synthetic chemistry to elaborate these into new, or difficult to source, molecules.

Thirty years after the production of the first generation of genetically modified plants we are now set to move into a new era of recombinant crop technology through the application of synthetic biology to engineer new and complex input and output traits. The use of synthetic biology technologies will represent more than incremental additions of transgenes, but rather the directed design of completely new metabolic pathways, physiological traits, and developmental control strategies. The need to enhance our ability to improve crops through new engineering capability is now increasingly pressing as we turn to plants not just for food, but as a source of renewable feedstocks for industry. These accelerating and diversifying demands for new output traits coincide with a need to reduce inputs and improve agricultural sustainability.
Xinfa Pharmaceutical Co. Xinfa Pharmaceutical is situated in the city of Dongying in the delta area of the Yellow River. Dongying is also the home of the Shengli Oil Field, the second largest oil production facility in China. The well- established infrastructure, ample land resources and friendly business investment environment enabled us to have rapid and sustained development throughout the last ten years. Xinfa Pharmaceuticals is housed in a 50 acre m2 plant.

Syngas , or synthesis gas , is a fuel gas mixture consisting primarily of hydrogen , carbon monoxide , and very often some carbon dioxide. The name comes from its use as intermediates in creating synthetic natural gas SNG  and for producing ammonia or methanol. Syngas is usually a product of coal gasification and the main application is electricity generation. Syngas is combustible and can be used as a fuel of internal combustion engines. Syngas can be produced from many sources, including natural gas, coal, biomass, or virtually any hydrocarbon feedstock, by reaction with steam steam reforming , carbon dioxide dry reforming or oxygen partial oxidation. Syngas is a crucial intermediate resource for production of hydrogen, ammonia, methanol, and synthetic hydrocarbon fuels. Syngas is also used as an intermediate in producing synthetic petroleum for use as a fuel or lubricant via the Fischer—Tropsch process and previously the Mobil methanol to gasoline process. Production methods include steam reforming of natural gas or liquid hydrocarbons to produce hydrogen, the gasification of coal,  biomass , and in some types of waste-to-energy gasification facilities.
Continuous Flow Chemistry enables researchers to both evaluate and produce synthetic intermediates and products that would otherwise be inaccessible using conventional batch techniques. Working closely together with the pharmaceutical and fine chemicals industry Chemtrix BV has developed a complete, easy to scale product portfolio for continuous processing from lab to industrial production scale. In Flow Chemistry, two or more reagents are continuously pumped into a flow-reactor, where they mix and subsequently react under thermal control. Flow Chemistry has some major advantages. Mixing can be achieved within seconds and reaction temperature can raised above the solvent's boiling point, resulting in faster reactions.

The synthesis of steroidal active pharmaceutical ingredients APIs such as sex hormones estrogens, androgens, and progestogens and corticosteroids is currently performed by a combination of microbiological and chemical processes. Several mycobacterial strains capable of naturally metabolizing sterols e. Most of the industrial microbial strains currently available have been improved through traditional technologies based on physicochemical mutagenesis and selection processes. Surprisingly, Synthetic Biology and Systems Biology approaches have hardly been applied for this purpose. This review attempts to highlight the most relevant research on Steroid Biotechnology carried out in last decades, focusing specially on those works based on recombinant DNA technologies, as well as outlining trends and future perspectives.

Skinner, Oakland, Charles H. Wilcoxen, Jr. Lorenzo, and George J. It deals with a new and more advantageous method for synthesizing glycerine in this way whereby high purity glycerine can be obtained efficiently and economically. It is known that by catalytic hydroxylation of allyl alcohol with a peroxide, most advantageously hydrogen peroxide, good yields of glycerine can be obtained. A wide variety of catalysts have been used for the reaction. These include tungstic acids as described and claimed in Bergsteinsson patent, U. Still other hydroxylation catalysts which can be used for the reaction, although generally they are less advantageous than the foregoing catalysts, are described in the survey on hydroxylation reported by Mugdan and Young in the Journal of the Chemical Society London , , pages
Selected natural products have long been considered as desirable targets for total synthesis due to their unique biological properties and their challenging structural complexity. Laboratory synthesis of natural compounds usually relies on target-oriented synthesis, involving the production, isolation and purification of successive intermediates, requiring multiple steps to arrive to the final product. A far more economical approach using common synthetic scaffolds that can be readily transformed through biomimetic-like pathways to a range of structurally diverse natural products has been evolved in the last decade, leading synthesis to new directions. This tutorial review critically presents the hallmarks in this field.
