Cis-4-(benzod 1',3'-dioxol-5'-yl)-5-(1-iodoethyl)-dihydrofuran-2-one and trans-4-(benzod1',3'-dioxol-5'-yl)-5-(1-iodoethyl)-dihydrofuran-2-one and a method for their simultaneous obtaining

摘要

the invention relates to racemicznych? - jodo -? - lactone ring of 1,3 - benzodioksolowym model 1 and 2 shown in figure and the way their simultaneous receive.method of simultaneously receiving racemicznych? - jodo -? - lactone ring of 1,3 - benzodioksolowym is that (e) - 4 - (benzo [d] [1 ', 3') dioksol - 5 '- yl) - shoe - 3 - en - 2 - he shall be carried out by czteroetapowej synthesis in jodolaktonu00f3w mixture which then is excreted in the form of pure by column chromatography with cis - 4 - (benzo [d] [1 ',3 '] - dioksol - 5' - yl) - 5 - (1 - jodoetylo) - dihydrofuran-2 - he and trans - 4 - (benzo [d] [1 ', 3') - dioksol - 5 '- yl) - 5 - (1 - jodoetylo) - dihydrofuran-2 - he. both received lactones may find application in the food industry.lactone of formula 1 can be used as a constituent of preparations to combat fitopatogennych filamentous fungi of the fusarium and lactone of formula 2 can be used to protect crops and cereal storage before insect pests.
