Independent workers with team spirit: A catalytic sequence that exploits the compatibility of (chiral) cationic iridium catalysts for the isomerization of primary allylic alcohols to aldehydes with organocatalysts has been developed for the highly enantioselective α functionalization of aldehydes (see scheme: up to 66 % yield, d.r. 49:1, 99 % ee). The reaction displayed useful generality with respect to both the nucleophile and the electrophile.
