Design and synthesis of fused polycycles via Diels–Alder reaction and ring-rearrangement metathesis as key steps (Beilstein Journal of Organic Chemistry)

Abstract Atom efficient processes such as the Diels–Alder reaction (DA) and the ring-rearrangement metathesis (RRM) have been used to design new polycycles. In this regard, ruthenium alkylidene catalysts are effective in realizing the RRM of bis-norbornene derivatives prepared by DA reaction and Grignard addition. Here, fused polycycles are assembled which are difficult to produce by conventional synthetic routes. Beilstein J. Org. Chem. 2015, 11, 1259–1264. doi:10.3762/bjoc.11.140
