Novel substituted propargyl alcohols of the formula: ##STR1## novel allylic alcohols of the formula: ##STR2## and; .delta.,.epsilon.-unsaturated ketones of the formula: ##STR3## are provided. In the above formulas, R represents a group of the formula: ##STR4## wherein X.sub.1 and X.sub.2 are both hydrogen atoms or wherein one of X.sub.1 and X.sub.2 is a hydrogen atom, the other jointly with Z represents a bond; Z jointly with X.sub.1 or X.sub.2 represents a bond or separately represent a hydrogen atom, a hydroxyl group or a lower alkoxy group; R.sub.1 and R.sub.2 are the same or different and represents hydrogen atoms or lower alkyl groups; n is 1 or 2; and when n is 2, X.sub.1, X.sub.2, X, R.sub.1 and R.sub.2 may be the same or different. These novel compounds are easily produced and are useful as perfumes and as interrelated intermediates for the production of terpenoid compounds.
