چکیده
The synthesis and characterization of 1,1,1′1′-tetrapinacolborylethane is conducted to study the functionalization that densely borylated small molecules through Cu-catalyzed coupling with allyl halides. A second allylic alkylation homoallyl triboronate products gave access mixed dihomoallyl diboronates. intramolecular concatenated version produced methylenecyclopentane-1,2-dipinacolboronic ester 2:1 diastereoselection on trans-diastereoisomer.
