摘要
The construction of the 13-membered para-cyclophane substructure in GKK1032As, a member of novel pyrrolidinone-containing bioactive natural products, has been explored. An efficient approach for this synthetically formidable object was found, which relied on an intramolecular 1,4-addition between a nitromethylene group and a vinyl ketone moiety both incorporated as side chains into the 6/5/6-tricyclic (the A/B/C-ring system) of the GKK1032s.
