Abstract
The dihydropyran and dioxan which may be obtained by the Prins reaction between allo-ocimene and formaldehyde have been discovered to possess attractive floral odours. They are useful as ingredients of compounded perfumery compositions. There novel triene alcohols are also produced by the Prins reaction which find use as intermediates in the preparation of the dihydropyrans and dioxans. The cis isomer of the dihydropyran may be converted into the trans isomer. The dihydropyran wherein at least 10% of the compound takes the form of the trans isomer is novel.
