Chemoselective Z-Olefin Synthesis via Rh-Catalyzed, Formate Mediated 1,6-Reduction

Rylan J. Lundgren, Zhongyu Wei, Ruohua Gui, Raphael Dada
Z-olefins are important functional units in synthetic chemistry; thus their preparation has received considerable attention. Many prevailing methods for cis-olefination are complicated by the presence of multiple unsaturated units or electrophilic functional groups. In this study, Z-olefin products are delivered via selective reduction of activated dienes using formic acid. The reaction proceeds with high regio- and stereoselectivity (typically >90:10 and >95:5 respectively) and preserves other alkenyl, alkynyl, protic and electrophilic groups.
