Derivatives of dihydropyran-2-iso-butyl-2,4-dimethyl-3,6-dihydropyran, 2-isobutyl-2, 4-dimethyl-5,6-dihydropyran and 2-isobugyl 2-metsh1-4-methylenetetrahydropyrami are known as a mixture isomers with a fruity citrus scent. The chain of the invention is new dihydropyran derivatives having a new scent note that are used as a hollow component in the perfume composition. The objective is achieved by a new chemical structure of the general formula. Compounds of formula (1) are obtained by depadr by chlorinating 4-methyl-4-chloro-3- (c-phenylethyl-tetrahydropyran in the presence of a basic agent, preferably sodium methoxide or potassium hydroxide, at 60-90-C The desired product is isolated as a mixture of isomers 4-methyl-3- ((i-phenylethyl) -3,6-dkgidropyran, 4-methyl-3- (ci.-phenylethyl) -5,6-dihydropyran and 4-methylene -3- (ot -phenylethyl) -tetrahydropyran as a percentage 35:40:25. The process is carried out for 5-7 hours with a ratio of the starting chloride: main agent equal to 1: 4. The starting 4-chloro-4-methyl-3 - ((i-phenylethyl) -tetrahydropyran is obtained by reacting 1-phenyl-1-chloroethane with 4-methyl-5,6-dihydropyran in the presence of zinc chloride as a catalyst in a ratio of 1: ( 1-1.2): (0.0035-0.0044) at 18-22 ° C for 6-8 hours. 4-Methyl-4-chloro-3- (c-phenylethyl) tetra1-idropy-) Accessible wounds, as obtained on the basis of 4-methyl-5,6-dihydropyran, which is a large-scale by-product of the production of isoprene according to Prince. Example 1. 4-M ethyl-4-chloro-3- (ot-phenyl ethyl) - tetrahydropyran. In a flask equipped with a reflux condenser and a thermometer, 14 g (0.1 mol) of 1-phenyl-1-chloroethane and 0.5 g (0.0035 mol) of powdered freshly zinc chloride, ground into a powder, will be placed and added dropwise during 15 min. 9.8 g (0.1 mol) 4-methyl-5,6-dihydropi-. wound at 22 ° C. Stirring is continued for 6 h, then the reaction mass is washed with 50 ml of water, extracted with 150 ml of ether, it is dissolved in calcium chloride. Distillation in vacuo gives 19.1 g (80%) of 4-methy-1-4-chloro-3- (e-phenylethyl) -tetrahydropyran with a bp. 104- 108 ° C / 2mm, 1 ° 1.5495, d Found,%: C 70.15; H 7.87; С b 14.62 С4Цт9СО Calculated,%; C, 70.44; H 7.96; C1 14.88.

Analogously to example 1 of 14 g (0.1 mol) of 1-phenyl-1-chloroztan and 11.8 g (0.12 mol) of 4-methyl-5,6-dihydropyran in the presence of 0.6 g (0.0044 mol ) Zinc chloride at 18 ° C for 8 hours gives 19.5 g (81.8%) of 4-methyl-Fchlor-3- (d-phenylethyl) -tetrahydropyran. Example 3. A mixture of 4-methyl-3- (o-phenylstsh I) -3,6-dihydropyrane, 4-methy ..- 3- (o-phenylethyl) -5,6-dihydropyran and 4-methylene-3- (oC -phenylethyl) -tetrahydropyran. 11.2 g (0.2 mol) of potassium hydroxide in 10 ml of methanol are heated with stirring to 60 ° C and 11.93 g (0.05 mol) of 4-methyl-4-chloro-3- ( (y-phenylstil) tetrahydropyran for 30 minutes, then continue heating at 90 ° C for an additional 6 hours. Then 30 ml of water are added to the reaction mixture, extracted with 200 ml of ether, dried with sodium sulfate. Distillation in vacuo gives 7.5 g (75%) mixtures of 4-methyl-3- (o1.-phenylethyl) -3,6-dihydropyran, 4-methyl-3- (cL-phenylethyl) - 5,6-dihydrupyran and 4-methylene-3- (° C -phenylethyl) -tetrahydropyran with a boiling point of 101-105 ° C / 1 mm, p 1.5378; 1.0033. Found: C 83.02; H 9.0.0 Ci4Hi80 Calculated,%: C, 83.16; H, 8.91. Example 4.
