Borylstannylation of alkynes with inverse regioselectivity: copper-catalyzed three-component coupling using a masked diboron
Keyword(s):
Masked boryl and stannyl moieties are smoothly installed into a carbon–carbon triple bond of diverse terminal alkynes under copper catalysis to provide cis-boryl(stannyl)alkenes in a straightforward manner. The regioselectivity is totally inverted to those of the previous borylstannylations, where a masked boryl moiety is attached to an internal carbon of alkynes.
