    Notizen: Abstract Research results are summarized from a series of insect juvenile hormone analogs derived from 2-(4-hydroxybenzyl)-1-cycloalkanones, which have been investigated at the Institute of Organic Chemistry and Biochemistry in Prague during the past 20 years. At present, practical application of several prospective structures for insect control is under investigation. Biological activity values were determined to delineate the most important subseries of compounds and the most promising insect juvenile hormone analogs selected from the subseries. Carbamates, and in particular compound 47 proved to be highly active against aphids, cockroaches, flies, and many other insect species.

    Oxime ethers as potential juvenoids: Synthesis of optical isomers (1990)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 1990 (1990), S. 847-852 
    Details
    ISSN: 0170-2041

    Thema: Chemie und Pharmazie
    Notizen: Two racemic juvenoids 5 and 6 and their optical isomers 10, 11, 17 and 18 having chiral centres in the aliphatic side chain were synthetized. The second chiral centre in the molecules remained racemic in all derivatives prepared. The absolute configurations of the optically active centres of the enantiomers were determined on the basis of the 1H-NMR spectral evaluation of the diastereoisomeric MTPA esters 12, 13, 19 and 20 derived from the intermediate alcohols 8 and 15. The optical purity was established by an HPLC analysis of the corresponding MTPA esters. The 1H-NMR spectra of all compounds as well as the CD spectra of all chiral isomers were measured and discussed.
