摘要：NOVELTY - A piperazine pyridine optical isomer of (11R, 14S) pyridine optical isomer (A3) and/or (11S, 14R) pyridine optical isomer (A4) is new. USE - Piperazine pyridine optical isomer. ADVANTAGE - The optical isomer has higher isomer activity than the existing industrial pyridine product. The method can remove the isomer of low efficacy and improves the effect of the pesticide. DETAILED DESCRIPTION - A piperazine pyridine optical isomer of (11R, 14S) pyridine optical isomer of formula (A3) and/or (11S, 14R) pyridine optical isomer of formula (A4) is new. INDEPENDENT CLAIMS are included for: (1) an agricultural composition comprising 0.001-99.99 wt.% optical isomers of pharmaceutically acceptable salt and pesticide and carrier or excipient; and (2) preparation of piperazine pyridine optical isomer.
