Esters derived from fatty acids and juvenoid alcohols of the general formula (I), in which X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom, R means methyl, ethyl, 1-propyl, 2-methylethyl or propargyl and R′ means saturated or unsaturated alkyl with 4 to 22 carbon atoms. Esters derived from fatty acids and juvenoid alcohols are produced by a reaction of a juvenoid alcohol of the general formula (II), in which X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom and R means methyl, ethyl, 1-propyl, 2-methylethyl or propargy] with a fatty acid chloride of the general formula (Ill): R′COC1 in which R′ means saturated or unsaturated alkyl with 4 to 22 carbon atoms, under the continuous stirring, at 0 to 70° C., using a convenient solvent, as toluene, xylene or benzene and under the presence of a base catalyst, as triethylamine, pyridine or quinoline. The compounds claimed in the claim 1 of the general formula (I) are applied for the insect population density control.
从脂肪酸和青少年醇衍生的酯的通式(I),其中X表示氧原子或NH基团,Y表示NH基团或氧原子,R表示甲基、乙基、1-丙基、2-甲基乙基或丙炔基,R'表示饱和或不饱和的烷基,其碳原子数为4至22。从脂肪酸和青少年醇衍生的酯是通过将通式(II)的青少年醇(其中X表示氧原子或NH基团,Y表示NH基团或氧原子,R表示甲基、乙基、1-丙基、2-甲基乙基或丙炔基)与通式(III)的脂肪酸氯化物进行反应而产生的:R'COCl,其中R'表示碳原子数为4至22的饱和或不饱和烷基,在连续搅拌下,在0至70°C下使用方便的溶剂(如甲苯、二甲苯或苯)和碱性催化剂(如三乙胺、吡啶或喹啉)的存在下。通式(I)的权利要求1中所要求的化合物用于控制昆虫种群密度。
