Abstract

Abstract : A variety of tetra‐, di‐ and monobromo derivatives of dienoates were prepared from parent polyunsaturated esters under mild conditions. According to proposed protocol the target bromoesters were easily obtained as a rule in good yields and high selectivity. Abstract : One isomer or another! Chemo‐ and stereoselectivity of dienoates bromination depends strongly on the substituent nature in starting ester and reaction conditions.
