Wolfgang Preuss is a notable inventor based in Monheim, Germany. He has made significant contributions to the field of steroid chemistry, holding a total of 9 patents. His work focuses on the development of steroid-20-carboxylic acid compounds and their production processes.

Latest Patents

Among his latest patents, Preuss has described novel steroid-20-carboxylic acid compounds and a process for their production. These compounds correspond to a specific general formula, where X represents halogen, particularly chlorine or bromine, or NH₂. The process involves dehydrating saturated starting compounds that are hydroxylated in the 11-position to form the 9(11)-ene-bond. This innovative method allows for the formation of 20-acid halides and dehydration in a single process step. Additionally, he has developed new Δ4-steroid compounds, which may contain a further double bond in the 1-position and an 11-oxygen function. These compounds are obtained from associated steroid-20-carboxylic acids through a reaction with a halogenating agent at controlled temperatures.
