The products formed by condensation of orcinol with 2-methyl-3-buten-2-ol, with geraniol, and with linaloöl in aqueous solutions of organic acids have been separated and identified. C-isoprenyl-and C-geranyl-orcinols are obtained as major products. Minor amounts of the corresponding hydrates, chromans, chroman hydrates, and hexahydroxanthene derivatives are also formed.
