BRASSINOSTEROIDS, PROCESS FOR THE PREPARATION THEREOF, AND PRODUCTS CONTAINING SUCH COMPOUNDS AND HAVING REGULATORY ACTION ON PLANT GROWTH

摘要

THE INVENTION CONCERNS NEW BRASSINOSTEROIDS. THEY MEET THE FORMULA: BR/ (CF DRAWING IN BOPI) BR/ IN WHICH R REPRESENTS A RADICAL ALKYL OR ALCENYL, Z REPRESENTS A RADICAL -CO-O-CH- CO-CH-, AND R AND R ARE DIFFERENT FROM ONE ANOTHER AND EACH REPRESENT HYDROGEN OR AN ACYL, OR STILL FORM TOGETHER A CARBONYL RADICAL OR A RADICAL BR/ (CF DRAWING IN BOPI) BR/ IN WHICH X REPRESENTS HYDROGEN OR A RADICAL ALKYL OR ALCOXY AND REPRESENTS HYDROGEN OR A RADICAL ALKYL, ALCOXY OR ARYL. /P P THESE COMPOUNDS ARE GROWTH SUBSTANCES. THEY WILL BE USED IN PARTICULAR TO ACT ON THE VEGETATIVE OR GENERATIVE DEVELOPMENT OF LEGUMES SUCH AS SOY.
