Abstract

The hydrovinylation of nopadiene gave a single 1,4-addition product (1) as an oil. A 3- step transformation of 3 gave 2,4-dinitrophenylhydrazone 6 as a crystalline compound. X-ray diffraction analysis of 6 confirmed the stereochemical assignments about the exocyclic olefin as well as at stereocenter C(3).
