3-Chloronorbornenone (R)-1a (98% ee) was obtained from trichloronorbornene 5 in two steps by the in situ generation of dichloronorbornadiene 2a with t-BuOK and desymmetrization with (−)-ephedrine, followed by hydrolysis with PPTS. The generality of this desymmetrization with (−)-ephedrine was tested with dibromonorbornadiene 2c and other substituted dichloronorbornadienes.

Abstract Norbornadienes that feature the properties of norbornadiene and of the ene-diyne in the same molecule have been prepared via a simple and high-yielding route starting fromdichlorobicyclo[2.2.1]hepta-2,5-diene (1).
A cross-linked copolymer containing repeating units derived from dicyclopentadiene and metathesis polymerizable halogen-containing cycloalkenes, a process for producing the copolymer, a process for producing a molded article from the copolymer and a polymerizable composition therefor.
