One-Pot FDCA Diester Synthesis from Mucic Acid and Their.
Mucic acid, C 6 H 10 O 8 or HOOC-(CHOH) 4-COOH (also known as galactaric or meso-galactaric acid) is an aldaric acid obtained by nitric acid oxidation of galactose or galactose-containing compounds such as lactose, dulcite, quercite, and most varieties of gum.
Here we present an alternative route of synthesis of mucic acid by means of biotechnology in Aspergillus niger and Hypocrea jecorina. In nature, mucic acid is the first intermediate in the D-galacturonate catabolic pathway in some bacteria, such as Agrobacterium or Pseudomonas.
THE POWER OF MANY. HunterNet is a network of manufacturing, engineering and specialist services companies located in the Hunter and Central Coast Regions of NSW.
A one pot-two step procedure for the synthesis of diethyl furan-2,5-dicarboxylate (DEFDC) starting from mucic acid without isolation of the intermediate furan dicarboxylic acid (FDCA) was studied.
Synthesis Essay Introduction Students who wonder how to write an AP English synthesis essay should begin with the synthesis essay introduction. In AP English test, synthesis essay, is a common phenomenon.

Galactaric acid is a hexaric acid resulting from formal oxidative ring cleavage of galactose. It has a role as a human metabolite. It is a conjugate acid of a galactarate(1-) and a galactaric acid anion. Galactaric acid is the dicarboxylic sugar acid resulting from oxidation glactose with dilute nitric acid.
Synthesis of a new type of mucic acid 1,4-lactone methyl ester 3-O-ferulate related to an extractive component isolated from Citrus sudachi, and its diastereomer has been achieved by employing stereodivergent dihydroxylation as a key step.The structures of the final products are fully characterized by spectroscopic methods and compared with that of the natural product.

In this exercise, the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride, the starting materials. Instead of using acetic acid, acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right.
