Paragraph 0045; 0046, (2019/05/16)
Belonging to the technical field of organic compound synthesis, the invention in particular relates to a preparation method of pemetrexed acid. The method is characterized by utilizing methyl p-formylbenzoate and malonic acid as the starting materials to synthesize the target product. Compared with the methods for synthesis of the compound reported in previous literatures, the method provided by the invention has the advantages of easily available raw materials, low price and no pollution, greatly reduces the production cost, and is suitable for large-scale industrial production. The method isa brand new synthetic route for the compound.
A biocompatible alkene hydrogenation merges organic synthesis with microbial metabolism

Organic chemists and metabolic engineers use orthogonal technologies to construct essential small molecules such as pharmaceuticals and commodity chemicals. While chemists have leveraged the unique capabilities of biological catalysts for small-molecule production, metabolic engineers have not likewise integrated reactions from organic synthesis with the metabolism of living organisms. Reported herein is a method for alkene hydrogenation which utilizes a palladium catalyst and hydrogen gas generated directly by a living microorganism. This biocompatible transformation, which requires both catalyst and microbe, and can be used on a preparative scale, represents a new strategy for chemical synthesis that combines organic chemistry and metabolic engineering. Reduction to practice: A hydrogenation reaction has been developed that employs hydrogen generated in situ by a microorganism and a biocompatible palladium catalyst to reduce alkenes on a synthetically useful scale. This type of transformation, which directly combines tools from organic chemistry with the metabolism of a living organism for small-molecule production, represents a new strategy for chemical synthesis.
