Latest Patents
Tonis Pehk holds a patent for a method involving the synthesis of Archiral (2-hydroxy-3-oxo-cyclopent-1-enyl) acetic acid alkyl, alkylphenyl, and phenyl esters. This patent describes a simple and efficient method for producing both enantiomers of homocitric acid gamma-lactone. The process is based on asymmetric oxidation of esters, followed by basic and acidic hydrolysis, culminating in the acidic lactonization of homocitric acid. The resulting homocitric acid salts are obtained through basic treatment of the gamma-lactone. The esters, conditions, and reagents used in this chemical conversion are crucial for the efficient production of homocitric acid gamma-lactone and its salts.
