Synthesis and domino metathesis of functionalized 7-oxanorbornene analogs toward cis-fused heterocycles
摘要:
Here, we report our strategy to synthesize structurally diverse cis-fused heterocycles via 7-oxanorbornene analogs. By the intramolecular Diels-Alder reaction of 3-iodoacrylamide, followed by the domino metathesis reaction, the cis-fused heterobicyclic skeleton was efficiently constructed in 5-8 steps.
