title: Synthesis of cyclic 1-alkenylboronates via Zr-mediated double functionalization of alkynylboronates and sequential Ru-catalyzed ring-closing olefin metathesis.
abstract: Synthesis of novel cyclic 1-alkenylboronates is accomplished through the zirconium-mediated regio- and stereoselective double functionalization of 1-alkynylboronates and the subsequent ruthenium-catalyzed ring-closing metathesis (RCM). The obtained substituted cyclic 1-alkenylboronates are transformed into o-terphenyl and triphenylene derivatives.
