Key words

propargyl diols - boron - Suzuki–Miyaura coupling

Significance

The authors report a step-economical and functional group tolerant method for the synthesis of tetra-, penta-, and hexa-substituted 1,3-butadienes from underivatized propargylic diols and aryl or alkenyl boronic acids in moderate to high yields.


#

Comment

The reported method can be applied to remarkably short syntheses of highly substituted benzofulvenes and aryl indenes through treatment of the cross-coupled products with acid.
