The larvae of the European leafbeetle Chrysomela lapponica use esters of isobutyric acid and (S)-2-methylbutyric acid as defensivesecretion. The acids are formed by the larvaefrom amino acids, as could be shown by experiments with labelled compounds. The alcohols taken up from the foodplant are either directly used for ester formation, like (Z)-3-hexenol (3) and 8-hydroxylinalool (1), or modified
N-methylaniline and asymmetric cyclopropylphosphonation reactions of N,N-diethylaniline derivatives with diazomethylphosphonates are reported. Optically active cyclopropylphosphonate derivatives were directly synthesized from diazomethylphosphonates and N,N-diethylaniline derivatives catalyzed by a Ru(II)-Pheox complex in one step in good yields and high diastereoselectivities (up to trans/cis = > 99:1<)
