摘要:An in vitro and/or in vivo method of producing malonic semialdehyde (MSA) or an anion or salt thereof and/or 3-hydroxypropionic acid (3-HP) or an anion or salt thereof is provided herein. The method may comprise two steps: (1) hydrating acetylenecarboxylic acid (ACA) or an anion or salt thereof by reacting the ACA or an anion or salt thereof with an ACA-hydrating enzyme to form a reaction product comprising malonic semialdehyde (MSA) or an anion or salt thereof; and (2) reacting the reaction product comprising MSA or an anion or salt thereof with one or more oxidoreductases in an oxidation-reduction (redox) reaction to produce 3-HP or an anion or salt thereof A pair of oxidoreductases may additionally recycle a cofactor, such as NADPH or NADH. Recombinant microbes and compositions are also provided herein which may include ACA-hydrating enzymes or variants thereof, and/or one or more oxidoreductase enzymes.

摘要:A process for the preparation of pyrazolone derivatives represented by the general formula ##STR1## wherein R is a hydrogen atom, an alkyl group, an allyl group, an aryl group or an aralkyl group, and R 1 and R 2 are, respectively, a hydrogen atom, an alkyl group or a phenyl group which may have a substituent, comprising reacting a 2,3-dihalocarboxylic acid derivative or a 2-haloacrylic acid derivative with a hydrazine derivative. A pyrazolone or 1-substituted-3-pyrazolones useful as intermediate starting materials for the synthesis of agricultural chemicals, medicine and chemical compounds can be easily and cheaply prepared from widely used industrial starting materials.

摘要:There is disclosed an imprinted polymer support for solid phase organic synthesis (SPOS). The polymer support being obtainable from a method that comprises providing a substrate and a mold, the mold having a defined surface pattern. A composition is placed between the defined surface pattern of the mold and the substrate. The composition comprises a polymerisation medium with at least one functional monomer and a free radical initiator. The composition is polymerised to form an array of polymer imprints adhered to the substrate.
