Synthesis and Testing of Compounds That Inhibit Soybean Cyst Nematode Egg Hatch

Soybean cyst nematode infestation continues to be a serious agricultural problem. As part of an interdisciplinary effort to identify a biorational solution to the problem, analogs of glycinoeclepin A, a natural hatching stimulus of the nematode, were prepared and tested. Several of the analogs were discovered to inhibit the hatching of soybean cyst nematode eggs. On the basis of the results of egg hatch tests, the minimum functionality for egg hatch inhibition appears to be a keto diacid
