2,2-Dimethyl-3- cyclopropane carboxylic

Compounds that affect Host Reactions. Examples of compounds which enhance or induce host reactions to pathogens include 2,2-dichloro-3,3-dimethyl-cyclopropane carboxylic acid (DDCC), probenazole, and fosetyl-Al (4). Although these chemicals do not stop the fungus from penetrating the plant, they are quite effective at preventing colonization through the enhancement of the host s resistance mechanisms. Further studies are needed to elucidate how these resistance mechanisms are triggered. [Pg.41]

The first example of asymmetric organometallic catalysis outside the area of polymer chemistry was the cyclopropanation of alkenes as described by Nozaki, Noyori et al. in 1966 [17]. The chiral catalyst used was a salen-copper complex 3 (Scheme 3), giving a maximum enantioselectivity of 10% ee. These low but well-established values initiated further research in this area. Later, Aratani et al. initiated the tuning of the structure of the copper catalyst at Sumitomo [18]. They were able to reach quite high level of enantioselectivity with copper catalyst 4. For example, 2,2-dimethyl-cyclopropane carboxylic acid was obtained in 92% ee, and subsequently used in a process to prepare cilastatine. [Pg.26]

Permethrinic acid has two enantiomer pairs and four isomers (2" = 4) (Table B33, Appendix B). The acid leaving group for permethrin, cypermethrin, and cyfluthrin is permethrinic acid. The structure of this acid is given in Table 3. Angerer and Ritter (1997) separated the methyl esters of cis- and trans-permethrinic acid on a polysiloxane capillary column by GC (Table C18, Appendix C). The carboxylic acids of several of these pyrethroids were also listed as trans- or cw-3-(2, 2-dichlorovinyl)-2, 2-dimethyl cyclopropane carboxylic acid. The acids may be separated on a CHIREX phase 3005 column (Phenomenex, 2320 W 205th Street, Torrance, CA 90501) by HPLC. [Pg.20]

R and R may be H, methyl, cyclopropyl, cyano, or ester groups. The phenylcarbene formed on irradiation of trans-l,2-diphenyloxirane has been trapped and identified in the form of a cyclopropane derivative in methanol in the presence of benzyl methyl ether and alkenes. Photolysis in the presence of 2,3-dimethyl-2-butene proceeds by cycloaddition with the formation of cyclopropane-carboxylic acid and oxetane derivatives (Eq. 368). ... [Pg.142]

More investigations have been performed with cyclopropyl ketones. The isomerization of the cis-cyclopropyl ketone 209 to its trans isomer 210 was only achieved by means of the rather basic dimsyl sodium in dimethyl sulfoxide at 60°C . Similarly, esters of cyclopropane carboxylic acids have been isomerized ... [Pg.770]
