developed based on an iridium-catalyzedallylicalkylation of phosphonates and Horner–Wadsworth–Emmons olefination. This two-step protocol uses easily accessible substrates and delivers C2-substituted skipped dienes bearing a C3 stereogenic center, generally with outstanding enantioselectivities (up to 99.5:0.5 er). This is the first catalytic enantioselective allylicalkylation of phosphonates, and
