Title: Erwin Kübel: Innovator in Retinoic Acid Production
Introduction
Erwin Kübel is a notable inventor based in Linz, Austria. He has made significant contributions to the field of chemistry, particularly in the production of retinoic acid, which has important applications in medicine and biology.
Latest Patents
Kübel holds a patent for a method of production of 9-cis-retinoic acid. This improved method involves a reaction between a β-formyl-crotonic acid C-Calkyl or phenyl ester and an isolated 9-(Z)—C-triarylphosphonium salt through the Wittig reaction in the presence of a base. The process results in the corresponding 9-(Z)-retinoic acid ester, which is then saponified with a base to yield the 9-(Z)-retinoic acid carboxylate. Following protonation with an acid, the desired 9-(Z)-retinoic acid is obtained. Additionally, the method enhances the enrichment and isolation of the 9-(Z)—C-triarylphosphonium salt.
