A polydicyclopentadiene derivative was obtained via ring-opening metathesis polymerization (ROMP) of acetoxy-substituted dicyclopentadiene (AcO-DCPD) using the Grubbs 1st generation catalyst. Analyses of the polymer microstructures indicate that polymers are linear. The glass transition temperatures (Tg) of the linear polymers range from 136°C to 159°C, which are much higher than that of linear polydicyclopentadiene.

The zeolite H-Beta catalyzes the retro-Diels-Alder reaction of a range of cyclopentadiene cyclo-adducts at moderate temperatures and ambient pressure, in the presence of an active dienophile. The active catalyst was identified and optimum reaction conditions established after screening a range of zeolites in the retro-Diels-Alder reaction of the cyclopentadiene adduct of cyclopentenone. Our results suggest that retro-Diels-Alder reactions of tricyclodecadienones are catalyzed by Bronsted acids and the high catalytic performance of H-Beta catalysts can be ascribed to the optimal balance between the number of acid sites and their strength as well as to the accessibility of these sites. The methodology was then applied to a series of alkyl derivatives of cyclopentadienylcyclopentenones to provide a viable alternative synthetic route to 4-alkylcyclopentenones and the versatility of the approach was demonstrated by the successful cycloreversion of N-cyclohexyl-2-azanorborn-5-ene.

The enantiopure dienes 8 and 24, which have been prepared by chemoenzymatic methods, engage in Diels-AIder cycloaddition reactions with maleic and citraconic anhydride to give adducts (e.g. 25-27) embodying the ABC-ring system associated with spinosyns A (1) and D (2).
