Design and synthesis of oxa-bowls via Diels-Alder reaction and ring-rearrangement metathesis as key steps

- Diels-Alder (DA) reaction is useful to design ring-rearrangement metathesis precursors.
- Norbornene derivatives prepared by DA reaction undergo ring-rearrangement metathesis.
- Oxa-bowls containing dienes are generated by ring-rearrangement enyne metathesis.
- Highly atom economic reactions are used to generate oxa-bowls.
- Green chemistry has been used to generate oxa-bowls.
