An enantioselective catalytic inverse electron-demand Diels-Alder reaction of salicylaldehyde acetal-derived oxocarbenium ions and vinyl ethers to generate 2,4-dioxychromanes is described. Chiral PCCP acids are found to be effective for a variety of substrates. Computational and X-ray crystallographic analyses support the unique hypothesis that a point chirality-induced, helically chiral anion dictates the absolute sense of stereochemistry in this reaction.
