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 instead by using KHF(2)/TsOH (see scheme). The utility of the... |

One-step (18)F labeling of biomolecules using organotrifluoroborates.
Nat. Protoc. 10(9) , 1423-32, (2015) Herein we present a general protocol for the functionalization of biomolecules with an organotrifluoroborate moiety so that they can be radiolabeled with aqueous (18)F fluoride ((18)F(-)) and used for positron emission tomography (PET) imaging. Among the β(+)... |

Synthesis of functionalized organotrifluoroborates via halomethyltrifluoroborates.
Org. Lett. 8 , 2031, (2006) [reaction: see text] Potassium bromo- and iodomethyltrifluoroborates have been prepared via in situ reaction of n-BuLi with dibromo- and diiodomethane, respectively, in the presence of trialkyl borates, followed by treatment with KHF(2). Moreover, a new synth... |

Highly stereoselective synthesis of cis-alkenyl pinacolboronates and potassium cis-alkenyltrifluoroborates via a hydroboration/protodeboronation approach.
J. Org. Chem. 73(17) , 6841-4, (2008) A number of alkynyl pinacolboronates bearing various functional groups were synthesized according to literature methods. These were then stereoselectively reduced to the cis-alkenyl pinacolboronates via hydroboration with dicyclohexylborane followed by chemos... |
