The front cover picture , provided by Laurent Ferrié, and co‐workers, is an artistic illustration, using pastel technique, of the functionalization of endoperoxyacetals mediated by mild Lewis acid systems such as InCl 3 /TMSCl and Sc(OTf) 3 . Indium and scandium are represented as humanoid workers helping in the cleavage of the acetate bond and bringing the allyl moiety necessary for a Sakurai reaction. The reaction conditions were improved, in comparison to previous reports, allowing an extension of the reagent scope, and more practical conditions.
