Substituted propargyl alcohols, allylic alcohols and unsaturated ketones, and methods for the production thereof

摘要

Novel substituted propargyl alcohols of the formula: <IMAGE> novel allylic alcohols of the formula: <IMAGE> delta , epsilon -unsaturated ketones of the formula: <IMAGE> are provided. In the above formulas, R represents a group of the formula: <IMAGE> wherein X1 and X2 are both hydrogen atoms or wherein one of X1 and X2 is a hydrogen atom, the other jointly with Z represents a bond; Z jointly with X1 or X2 represents a bond or separately represent a hydrogen atom, a hydroxyl group or a lower alkoxy group; R1 and R2 are the same or different and represents hydrogen atoms or lower alkyl groups; n is 1 or 2; and when n is 2, X1, X2, X, R1 and R2 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.
