Asymmetric Synthesis of 1-Heteroaryl-1-arylalkyl Tertiary Alcohols and 1-Pyridyl-1-arylethanes by Lithiation-Borylation Methodology [PDF]

, 2013
The synthesis of highly enantioenriched alpha-heterocyclic tertiary alcohols has been achieved via lithiation-borylation of a configurationally stable lithiated carbamate and heterocyclic pinacol boronic esters followed by oxidation. Protodeboronation of

Boronic Acid-Based Electrochemical Sensors for Detection of Biomolecules

International Journal of Electrochemical Science, 2013
Boronic acids can form reversible covalent bonds with 1, 2- or 1, 3-diols to generate five or six-membered cyclic complexes. Thus, boronic acid functionalized compounds and materials have attracted much attention in both chemistry and biology as the ...

Chemoselective Suzuki-Miyaura cross-coupling via kinetic transmetallation [PDF]

, 2016
Chemoselective Suzuki-Miyaura cross-coupling generally requires a designed deactivation of one nucleophile towards transmetallation. Here we show that boronic acids can be chemoselectively reacted in the presence of ostensibly equivalently reactive ...
