Abstract

Disclosed is to a laevorotatory enantiomer of the configurational stereoisomer of difethialone, named hetero-stereoisomer, the formula of which is 3-(4′-bromobiphenyl-4-yl)-1-(4-hydroxythiocoumarin-3-yl)-1,2,3,4-tetrahydronaphthalene, in which carbons 1 and 3 of the 1,2,3,4-tetrahydronaphthalene group have different absolute configurations.
