PROCESS FOR PREPARING AZETIDINE COMPOUNDS COMPOSITIONS CONTAINING THEM METHOD OF PRODUCING F1 HYBRID SEED AND F1 HYBRID SEED THUS PREPARED

摘要

Azetidine compounds of general formula …CHEM… or an acid addition salt thereof, wherein R represents a hydrogen atom or an acyl group; R1 to R6 are hydrogen, alkyl, aryl or other groups; and Z is a carboxyl group or a derivative thereof, have useful properties by rendering the anthers of plants sterile. By cross-pollination F1 hybrid seed may thus be prepared. The compounds may be prepared by hydrolysis/alcoholysis of the corresponding nitrile compounds, which are also novel.
