摘要:
The (-)(-) diastereoisomers of the .alpha.-cyano-3-phenoxybenzyl and .alpha.-ethynyl-3-phenoxybenzyl esters of 1-(4-ethoxyphenyl)-, 1-(4-chlorophenyl)-, and 1-(3,4-methylenedioxyphenyl)-2,2,3,3-tetrafluorocyclobutane carboxylic acid.
摘要:
Substituted styrylcyclopropanecarboxylic acid esters of the formula ##STR1## in which R represents C.sub.1-4 -alkyl or an alcohol radical customary in pyrethroids,R.sup.1 represents alkoxy or alkylthio, either of which is optionally substituted by halogen andR.sup.2 represents hydrogen or alkoxy, orR.sup.1 and R.sup.2 together represent optionally halogen-substituted alkylenedioxy, andR.sup.3 represents hydrogen or chlorine,exhibit arthropodicidal activity. A novel synthesis is shown involving reaction of ##STR2## in the presence of an alkali metal cyanide to produce an end product wherein R is an .alpha.-cyano-3-phenoxybenzyl ester. ##STR3## is reacted with ##STR4## in the presence of a base to produce certain novel intermediates.
摘要:
Compounds of the general formula I ##STR1## wherein R.sup.1 is hydrogen or a methoxy, ethoxy, propoxy, butoxy, tetrafluoroethoxy, methylthio, ethylthio, propylthio, fluoro, chloro, bromo, methyl, ethyl, or nitro group, and R.sup.2 is hydrogen or a methyl group, or R.sup.1 and R.sup.2 together form a methylenedioxy group;R.sup.3 is hydrogen, or a lower alkyl group, or one of the following groups (a) to (f):(a) 3-phenoxybenzyl(b) 2-benzyl-4-furylmethyl(c) .alpha.-cyano-3-phenoxybenzyl(d) 3,4-methylenedioxybenzyl(e) .alpha.-ethynyl-3-phenoxybenzyl(f) .alpha.-cyano-3-(4'-chlorophenoxy)-benzyland Y.sup.1, Y.sup.2, Y.sup.3, Y.sup.4, Y.sup.5 and Y.sup.6 are the same or different groups and each is hydrogen or a fluoro, bromo or chloro group, with the proviso that when R.sup.1 is hydrogen, fluoro, chloro, bromo or methyl and R.sup.2 is hydrogen, then one of Y.sup.1 to Y.sup.6 is other than hydrogen.The compounds in which R.sup.3 is one of groups (a) to (f) are insecticides.

摘要:
Novel anti-atherosclerosis agents having the formula, ##STR1## wherein R is hydrogen or lower alkyl, n and m each signify an integer of 4 - 6, and A is hydrogen or a group of the formula, ##STR2## WHEREIN R and m have the same meanings as defined above. These compounds are produced, for example, by reacting a bisphenolic compound of the formula, ##STR3## with chloroform and a ketone compound of the formula, ##STR4## in the presence of an alkali. Alternatively, they are produced by reacting the bisphenolic compound with .alpha.-halogeno- or .alpha.-hydroxycarboxylic acid derivative of the formula, ##STR5## wherein R and m have the same meanings as defined above, and X is halogen or hydroxyl.
