Rearrangement and radical puzzle: Chiral epoxides, silylated acetamides, and stable radical TEMPO provide, with the help of ferrocenium hexafluorophosphate, dioxygenated carbonylcompounds, which serve as versatile radical cyclization precursors.

Two highly convergent syntheses of a fully protected C1−C19 polyol subunit of the brasilinolide family of immunosuppressive macrolides are described, exploiting boron-mediated 1,5-anti aldol couplings to form the C8−C9 and C13−C14 bonds.
Four tetrahydroquinoline-based chiralcarbeneprecursors were synthesized using unsymmetrical N,N′-diarylformamidines and chiral 2-allyloxiranes as starting materials. A representative NHC–gold complex has been prepared and fully characterized, the crystal structure of which reveals an intramolecular Au⋯H–C(sp3) interaction between Au(I) and the hydrogen atom of the isopropyl moiety in the N-aryl group
