He has made significant contributions to the field of chemical processes, particularly in the area of transesterification and the conversion of acid derivatives. His innovative approach has implications for the production of sensitive biomolecules.

Latest Patents

Muller holds a patent for a process that employs amidine or amidine base and a metal compound in the presence of an alcohol or water to transesterify or saponify esters or amides. This process operates under relatively mild conditions, making it especially suitable for the production of optically active substances and biomolecules, such as peptides, amino acids, and nucleic acids. These compounds are sensitive to elevated temperatures, extreme pH values, and prolonged reaction times, which can lead to racemization or denaturation. The conditions also find utility in solid phase systems. When amino acid or peptide esters are saponified, the reaction is facilitated by lithium hydroxide alone under mild conditions. The use of an amidine base, particularly DBU or DBN, in combination with a metal salt accelerates the reaction significantly, allowing even sensitive acid derivatives to be processed under gentle conditions. This amidine-based system is advantageous for the manufacture of complex esters and the gentle splitting of peptides from carriers.
