Diastereoselective Synthesis of Axially Chiral Skipped Ene-Allenes Containing a Quaternary Stereocenter by Cyclopropene-Allene Metathesis
{{output}}
Functionalized skipped ene-allenes (1,4-enallenes) bearing an all‑carbon quaternary stereocenter were prepared by a diastereoselective ring-opening metathesis of mesomeric cyclopropene and allene for the first time. A strategic pairing of a broad range of all... ...
