Natural rubber (poly(1,4-cis-isoprene), NR) is a polymer of considerable industrial importance due to its exceptional properties. It is mostly produced from the cultivation of Hevea brasiliensis, and to a limited extent from Parthenium argentatum. Till date none of the synthetic equivalent of NR exists. Recently we suggested that the mechanism of NR biosynthesis is based on carbocationic polymerization, similarly to that of natural oligoisoprenoids forming by enzyme-catalyzed prenylation. In this article we present proof of concept of a new bio-inspired synthetic route towards the synthesis of polyisoprenes based on carbocationic polymerization initiated by dimethyl allyl bromide (DMABr)/TiCl4. It is shown that using this strategy, 1,4-oligoisoprene carrying a dimethyl allyl head group is produced in both cis and trans configurations, together with cyclized sequences< Leer menos
