A convenient synthetic route of deuterium-labeled D5-cyhalothrin, D5-fenpropathrin, and D5-fenvalerate is described with 98.7%, 98.5%, and 98.3% isotopic enrichment and high chemical purities using D6-phenol as labeled starting material. These structures and isotope-abundance were confirmed by 1H NMR and mass spectrometry. The prepared D5-cyhalothrin, D5-fenpropathrin, and D5- fenvalerate can be used as a standard internal reagent for the determination of residual pyrethroids of food and environment.
Chiral β‐aryl propanamine is an important structure unit of bioactive molecules or drugs. But its efficient synthesis remains a challenging task. In this study, several enantiocomplementary imine reductases capable of dynamic kinetic resolution‐reductive amination of sixteen 2‐phenylpropanal derivatives of diverse structural characteristics with four different amines were identified through screening 196 imine reductases. Furthermore, (
