REYES-GOMEZ, Sonia; MONTIEL, Raúl  e  TLENKOPATCHEV, Mikhail A.. Chicle Gum from sapodilla (Manilkara zapota) as a Renewable Resource for Metathesis Transformations. J. Mex. Chem. Soc [online]. 2018, vol.62, n.1, 00007. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v62i1.581.

In this study, we report on for the first time the self-metathesis of the chicle gum and cross-metathesis of the chicle gum rubber isolated from the gummy latex of sapodilla (Manilkara zapota) with orange oil, β-pinene and, methyl methacrylate using the Ru-alkylidenes Hoveyda-Grubbs and Grubbs second generation catalysts. There were obtained terpene- and ester-terminated oligoisoprenes, with good yields and selectivities. The present results are a promising starting point for the application of this underexploited renewable resource as a new feedstock for metathesis transformations.

Palavras-chave : Manilkara zapota; chicle gum; essential oils; metathesis; ruthenium catalysts; oligoisoprenes.
