Abstract

A method of acylation of phloroglucinol in the presence of a Friedel Crafts catalyst which is effected in the presence of nitromethane and dichloromethane so as to produce an acylphloroglucinol. The acylphloroglucinol is reacted with a compound selected from .gamma.,.gamma.-dimethyl allyl bromide and 2-methyl-but-3-ene-2-ol in the presence of a weak Lewis acid and in an organic solvent to produce a 4-desoxyhumulone which is then oxidized to produce a corresponding humulone.
