“1,1-Bisborylalkane: New Class of Organoboron Compound

for the Chemo, Regio and Stereoselective Organic Transformations”

 

1,1-Organodimetallic reagents are valuable starting materials for the construction of multifunctionalized molecules. Among them, 1,1-diborylalkanes, which contain two boryl groups at the same carbon center, are particularly attractive due to their ease of handling, non-toxicity, stability, and propensity to undergo a variety of organic transformations. In this context, our lab is highly interested in the development of regio, chemo and stereoselective organic reactions using 1,1-diborylalkanes as new types of organodimetallic reagents.

In this seminar, the details about our recent findings using 1,1-diborylalkanes in a range of organic transformations will be presented including 1) copper-catalyzed SN2’-selective allylic substitution reactions of allylic chlorides with1,1-diborylalkanes 2)the chemo- and diastereoselective alkylation ofN-tert-butanesulfinyl aldimines. 3) an unprecedented transition-metal-free deborylative alkylation of pyridine N-oxides using 1,1-diboryl-alkanes as alkyl sources and 4) an unusual chemoselective coupling of 1,1-diborylalkanes for the transition-metal-free borylation of aryl and vinyl halides.
