Adopting [11C + 3C] synthetic strategy, Li and Schwarz synthesized the olefins through the "one-pot" reaction of borane reagents by using hydroboration
in 18% overall yield .
(1974) A stereoselective synthesis of trans-1,4-dialkyl-1,2,3-butatrienes via hydroboration
We encouraged by the previous results  on hydroboration
of alkenes to alcohols with DMANB under microwave irradiation and further expand its utility as a hydride source, we undertook a series of compounds for functional group reduction by DMNAB under microwave irradiation.
of the diene forming the pheromones are found to yield the required Z-11-hexadecenol alcohol, but the hydroboration
should be regioselective towards the terminal double bond.
Rovia I Virgili, Spain), presents 15 papers demonstrating some of these applications, covering transformations such as hydrogenation, hydroamination, hydroboration
, C--C bond formation, carbonylation, and cyloadditions, as well as recent catalytic system using iridium nanoparticles and the use of relevant ligands as carbenes and pincer ligands.
His research involves catalyst system development and mechanistic elucidation for rhodium-catalyzed hydroboration
In the light of the information referred to above we made an attempt to obtain diketones 2 and 3 directly from lactone 1 by hydroboration
Primary amine functionalization was completed in refluxing THF by performing hydroboration
with 9-BBN followed by amination with hydroxylamine-o-sulfonic acid.
At first, hydroboration
of 5,6-double bond for the acetonide derivative (56) and the following oxidation of the resulting 6[alpha]-hydroxyl group into the oxo group gave 6-oxo derivative (57).
The pendant olefin is then converted into an alkyl borane by hydroboration
and the ring is formed using Suzuki-Miyaura technology (Scheme 1).

and hydroxylation of flav-3-enes," Australian Journal of Chemistry, vol.
These organosilica hybrid materials with crystalline mesoporosity, tailored through organic chemistry to be mono-, hi- or tri-functional, offer unique potential for scientific and technological advances in numerous application areas because the organic function and the inorganic framework can be tailo red through chemistry to tune their mechanical, electrical, optical, magnetic, catalytic, separation and chemical reactivity properties (see the group's recent paper 'Novel Bifunctional Periodic Mesoporous Silicas, BPMOs -- Synthesis, Characterization, Properties and in situ Selective Hydroboration
-- Alcoholysis of Functional Groups', Journal of the American Chemical Society, 123, 8520-8530, 2001).
