One-Pot Aldol Cascade for the Preparation of Isospiropyrans, Flavylium Salts, and bis-Spiropyrans

One-Pot Aldol Cascade for the Preparation of Isospiropyrans, Flavylium Salts, and bis-Spiropyrans

We probed tandem aldol condensations of sixteen <i>o</i>-hydroxyacetophenones, carrying electron-withdrawing and -donating groups at positions 4 and 5, using five molar equivalents of SiCl<sub>4</sub> in anhydrous ethanol. Substrates carrying electron-withdrawing groups (EWGs...
