The first enantioselective vinylogous Mukaiyama-type dearomatisation of heteroarenes under anion-bindingcatalysis is presented. A recyclable tetrakistriazole catalyst was used for the enantiocontrol of the remote vinylogous active position of silyl dienol ethers. This approach provided chiral heterocycles bearing α,β-unsaturated chains with complete regioselectivity and excellent enantioselectivities
