Efficient and practical synthesis of dissymmetrical ethers of 4-nitrocatechol
An efficient and practical synthesis of dissymmetrical ethers of 4-nitrocatechol from 5-nitrosalicyladehyde and 2-hydroxy-5-nitroacetophenone via Baeyer-Villiger oxidation is described. These dissymmetrical ethers are useful in the synthesis of various coccidiostats and other important pharmaceutical intermediates. Copyright Taylor & Francis Group, LLC.
