摘要:
Provided is an alicyclic alcohol compound which can be used as a raw material for a compound perfume, and which has excellent floral-green-like aromas which are crisp and fresh; also provided are a manufacturing method for the same, and a perfume composition which contains the alicyclic alcohol compound. An alicyclic alcohol compound having a specified structure represented by chemical formula (1) has excellent floral-green-like aromas which are crisp and fresh; and a method for manufacturing the alicyclic alcohol compound represented by chemical formula (1) by reacting, in the presence of hydrogen fluoride, 1-isopropyl-4-methylcyclohexene and carbon monoxide, reacting the resulting 4-isopropyl-1-methylcyclohexane carboxylic acid fluoride with alcohol, and, after having acquired a cyclohexane carbonyl compound, reducing the cyclohexane carbonyl compound.

A process for preparing a compound of general formula ##STR1## where Ar represents an optionally substituted aromatic or heteroaromatic group, the process comprising reacting a compound of general formulaAr--C(L.sup.1).sub.2 Cl (II)where each L.sup.1 independently represents a leaving group (preferably a chlorine atom), with water in the presence of a Lewis acid and a chlorocarbon solvent which includes at least two chlorine atoms, is disclosed.
摘要:
Compounds of the formula ##STR1## wherein R.sup.1 is an acyl group or certain optionally halo-substituted hydrocarbyl groups, and X is --CH.sub.2 CH(OCH.sub.3).sub.2, --CH.sub.2 CHO, --CH.dbd.CHOR.sup.2 in which R.sup.2 is acyl, --CHO,--C(O)Cl, --C(O)Br or --C(O)OR in which R is H, a salt-forming cation, an alkyl group or the residue of a pyrethroid alcohol are new pesticides or intermediates therefore. The compounds are prepared using a multi-step synthesis starting from the natural terpene, 3-carene.

WHEREIN EACH G independently represents hydrogen or straightchain alkyl of from one to six, both inclusive, carbon atoms; G'' represents hydrogen or acetyl; R represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms; R'' represents halo, alkoxy containing from one to six both inclusive, carbon atoms in the alkyl group, hydrogen or alkyl of from one to six, both inclusive, carbon atoms; each R'''' independently represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms; each R'''''' independently represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms or both R'''''' groups taken together represent oxo(-0); X represents halo; and each n independently represents an integer of from zero to one, both inclusive. The terms ''''halo'''' and ''''halide'''' are employed herein to designate occurrences of bromine, chlorine and iodine. The adamantane compounds of formula VII AND VIII are useful as agents to achieve a depressant action on the central nervous system of warm blooded animals. The adamantane compounds of formulas I, II, III, IV, V and VI are useful as intermediates in the synthesis of the compounds of formulas VII and VIII.
The present invention is directed to adamantane compounds of the formula:
