A novel domino sequence facilitates the rapid assembly of polysubstituted tetrahydropyrans. The one‐pot relay process generates up to three new stereogenic centers, including a tetrasubstituted carbon center, in a highly concise and convergent fashion from simple starting materials.
An eco-friendly synthesis of cycliccarbonates through a Lewisacidcatalyzed cyclization of tert-butyl carbonates is described. These cycliccarbonates are precursors of 1,2- and 1,3-diols, and the developed method was applied to a short synthesis of a diarylheptanoid, (3S,5S)-alpinikatin.
