CAS 8003-34-7. C21H2805. One of the four primary active insecticidal principles of pyrethrum flowers. It is the 3-(2-butenyl)-4-methyl-2-oxo-3-cyclopen-ten-l-yl ester of chrysanthemumdicarboxylic acid monomethyl ester. [Pg.304]

Monosaccharide oxiranes undergo the homo-Horner reaction with phosphoryl-substituted carbanions to give monosaccharides fused with a cyclopropane ring. " a-D-Mannopyrano-side 9, a precursor in an enantiospecific route to (4-)- and ( —)-chrysanthemumdicarboxylic acids, was synthesized in 50% yield by the reaction of methyl 2,3-anhydro-4,6-0-benzylidene-a-D-allopyranoside (8) with ethyl 2-(diethoxyphosphoryl)propanoate. " ... [Pg.838]

Further papers of interest in this section concern the decomposition of alkyl diazoacetates in 2,5-dimethylhexa-2,4-diene in the presence of chiral copper complexes (cf.
