CHRYSANTHEMIC ACID DERIVATIVES, PRODUCTION AND USE OF THEREOF |
| abstract |
Optically active or racemic chrysanthemate esters of formula (I) are new. (where R1 and R2 are H, halogen or lower alkyl, or one of R1 and R2 can be lower alkoxycarbenyle; R3 is H, lower alkyl or 1-alkenyl). (I) are used in preparing pyrethrins of formula (II): (II) are known insecticides. As well as being intermediates for preparing (II), cpds. (I) themselves have insecticidal activity, e.g. giving knock-down times (KD50) of 20-50 min. against Musca domestica and Blattella germanica. Specific (I) includes 1 beta-hydroxy-2 beta-(cis-2-butenyl)-3-methylene-4 beta-cyclopentyl circled positive -trans-chrysanthemate. |
