Allylmalonate as an Activator Subunit for the Initiation of Relay Ring‐Closing Metathesis Reactions

Abstract

Passing the baton: The relay ring-closing metathesis (RRCM) reaction of complex polyenes 1 has been studied. Several relay subunits (T) were examined and many did not sufficiently activate the RRCM. An allylmalonate-containing relay subunit solved this problem, and efficiently lead to the diene 2. TIPS=triisopropylsilyl.
