Abstract
Since 1951 it is known that methanolic alkaline isomerization of humulone produces a mixture of crystalline isomers. This paper shows that the mixture contains the four diastereoisomers with structures 12, 13, 14 and 15 of chart III. It is proposed to name these substances trans‐spiro‐isohumulone I and II and cis‐spiro‐isohumulone I and II respectively.
