series of N‐pyridylpyrazolo‐5‐methyl amines and their derivatives were designed and synthesized. Among the 22 target compounds obtained, bioassays indicated that some of the target compounds exhibited good insecticidal activities against Plutella xylostella (P. xylostella) and Spodoptera frugiperda (S. frugiperda). In particular, compound 9j revealed the best insecticidal activity against P. xylostella,
The invention provides novel cyclic dipeptide enantiomers comprising (R)-histidine or a derivative thereof as one of the amino acid residues. These compounds are useful a catalysts for production of (S) -α-cyanomethyl alcohols from aldehydes.

Novel alcohols of the formula:
where R3 is hydrogen are useful intermediate compounds in the preparation of insecticidal esters. The insecticides are compounds in which R1 is a substituted -vinylcyclop- ropanecarbonyl group, a tetramethylcyclopropanecarbonyl group, or a chlorophenyl- 2-methylpropylcarbonyl group.
The compounds are prepared by reacting a compound of the formula:
