Humulinic acid contains chiral centra at C 4 and C 5 and can therefore theoretically occur in four optically active stereoisomers. The diastereoisomeric forms are at the same time trans and cis isomers of each other (formerly humulinic acids A and B). 5 This paper concerns the isolation and characterization of the trans and cis co‐ and ad‐humulinic acids and the separation of racemic trans humulinic acid in its enantiomorphs.
