INTRODUCTION
Teprenone (Geranylgeranylacetone, GGA) is a mixture of the all-trans and mono-cis isomers of 6,10,14,18-tetramethyl-5,9,13,17-nonadecatetraen-2-one (in a weight ratio of 3:2). It is an acyclic isoprenoid compound with a structure like retinoids and is widely used for the treatment of gastrointestinal ulcers.
MANUFACTURE
Geraniol is first transformed into geranyl acetone through a two-step process involving in-situ bromination and substitution followed by decarboxylation. The resulting geranyl acetone is then converted to trans-farnesol via a Wittig reaction, followed by reduction of the corresponding ester. Subsequently, trans-farnesol undergoes a series of controlled reactions, including tosylation, substitution, decarboxylation, Grignard reaction, and oxidation, ultimately yielding teprenone.
