Graphical Abstract

Spiro compounds: An organocatalytic asymmetric method for the Curn:x-wiley:14337851:media:ANIE201204274:tex2gif-inf-2H functionalization of the α position of racemic cyclic ethers has been developed. The transformation, mediated by catalytic amounts of an imidazolidinone and strong acid, involves a tandem 1,5-hydride transfer/cyclization and provides access to a structurally diverse series of chiral spiroethers with high levels of enantioselectivity (see scheme).
