Electrochemical hydroxylation of organoboron compounds.
Cathodic hydroxylation of organoboron compounds was successfully performed under an oxygen atmosphere, producing the corresponding phenol derivatives with high selectivity and efficiency.
متن کامل[Synthesis of indole compounds using multifunctional synthons].
This review describes a synthesis of indole compounds using multifunctional synthons. The multifunctional synthons, trienes and gramines, were respectively synthesized using Pd-catalyzed tandem cyclization/cross-coupling reaction of indolylborate with vinyl bromide, and reaction of indolylcuprate with iminium chloride. As an application of the multifunctional synthons to the indole alkaloids sy...
متن کاملNew synthetic transformations via organoboron compounds
It was previously reported that the palladium-catalyzed cross-coupling reaction of 1-alkenylboron compounds with various vinylic or aryl halides in the presence of base provides the corresponding coupling products in high yields, stereoand regioselectively. The recent progress of such reactions, including the reaction of sterically hindered arylboronic acids with sterically hindered haloarenes,...
متن کاملNatural Product Synthesis
The Lycopodium alkaloids are a family of structurally complex natural products, which have provoked long-term interests in their total syntheses because of their unique and fascinating architectures and potential biological activities. In particular, fawcettimine-type Lycopodium alkaloids, such as fawcettimine (1) and fawcettidine (2) (Scheme 1), have attracted broad attention from the syntheti...
متن کاملAsymmetric Hydrogenation of 1-Phenylethenylboronic Acid and Esters for the Synthesis of Chiral Organoboron Compounds
The hydrogenation of ethanediol 1-phenylethenylboronic ester was carried out at -20 °C under the atmosphere of hydrogen (9 atms) in the presence of [Rh(cod)2]BF4/(R)-BINAP (3 mol%). After alkaline hydrogen peroxide oxidation, the reaction gave 1-phenylethanol with 80%ee.
