Novel substituted propargyl alcohols of the formula: ##STR1## novel allylic alcohols of the formula: ##STR2## .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.
提供了一种新颖的替代炔丙醇的化学式:##STR1##,一种新颖的烯丙醇的化学式:##STR2##,以及一种δ,ε-不饱和酮的化学式:##STR3##。在上述化学式中,R代表一个化学式为:##STR4##的基团,其中X₁和X₂都是氢原子,或者其中一个是氢原子,另一个与Z共同表示键合;Z与X₁或X₂共同表示键合,或分别表示氢原子、羟基或较低的烷氧基;R₁和R₂相同或不同,表示氢原子或较低的烷基基团;n为1或2;当n为2时,X₁、X₂、X、R₁和R₂可以相同也可以不同。这些新颖化合物易于生产,可用作香水,并用作萜类化合物的生产的相关中间体。
