Diversity oriented approach to crownophanes by enyne metathesis and Diels-Alder reaction as key steps

摘要

Various crownophanes are assembled starting with simple phenol derivatives such as catechol, resorcinol, and hydroquinone. Here, cross-enyne metathesis (CEM) and Diels-Alder (DA) reaction have been used as key steps. This strategy has embedded six diversity points.
