Abstract

4,4-Dichloro-2-butenoic acid derivatives are shown to undergo a rare dimerization process when reacted with bis(pinacolato)diboron under copper catalysis. The reaction provides densely functionalized products with excellent levels of chemo-, regio-, and diastereoselectivity. This high degree of functionalization makes these products versatile building blocks for the stereoselective synthesis of chlorocyclopropanes.
