Multiproduct terpene synthases TPS4-B73 and TPS5-Delprim from Zea mays exhibit isotopically sensitive branching in the formation of mono- and sesquiterpene volatiles. The impact of the kinetic isotope effects and the stabilization of the reactive intermediates by hyperconjugation along with the shift of products from alkenes to alcohols are discussed.

Preparation of pure γ-curcumene (3) described by Birch in 1949 via dehydratization of the alcohol 5 with SOCl2/pyridine was not reproducible.Mixtures of α-, β-, and γ-curcumene (1-3) were obtained even with POCl3/pyridine or Burgess reagent.Analogously the secondary alcohol 20 yielded mixtures of 3 and the 1,3-dienes 21 and (presumably) 22. - Li/NH3 reduction of the tert. benzyl alcohol 8 afforded after work-up directly the dienone 15 which with MeLi gave the dehydro derivative 16 of zingiberenol (17).
