摘要
An efficient approach to tetrasubstituted alkenylboronates via a cascade borylation/B-O elimination of propynols and B(2)pin(2) was disclosed. A series of tetrasubstituted alkenylboronates were readily furnished with this strategy in good yields, with further transformations leading to tetrasubstituted alkenes and beta-diketones demonstrating the synthetic potential of the alkenylboronates constructed by this strategy as versatile intermediates in organic synthesis.
