Abstract

A chemoselective DBU-promoted elimination of vicinal dibromoalkanes having an adjacent O-functional group enables an efficient one-pot method for bromination-elimination of allyl alcohol derivatives to give 2-bromo allyl alcohol derivatives. Moreover, an efficient one-pot method for Sonogashira coupling was also achieved.
