Diastereodivergent synthesis of trisubstituted alkenes through protodeboronation of allylic boronic esters: application to the synthesis of the Californian red scale beetle pheromone.

Angew. Chem. Int. Ed. Engl. 51(50) , 12444-8, (2012)

E-allylic boronic esters undergo a highly diastereoselective protodeboronation with TBAF⋅3 H(2)O to give Z-trisubstituted alkenes. The selectivity can be switched to give predominantly the E-alkene in...

One-step (18)F labeling of biomolecules using organotrifluoroborates.
