Reactivity of Carbon Nucleophiles with Disubstituted Tricarbonyl(pentadienyl)iron(1+) Cations: Application to the Synthesis of Lasiol and Epi-lasiol
Donaldson, William A.,Jin, Myung-Jong
, p. 8787 - 8794 (1993)
The reactions of 1,2-dimethyl-, 1-phenyl-2-methyl-, 1,4-dimethyl-, and 1-phenyl-4-methyl- substituted tricarbonyl(pentadienyl)iron(1+) cations (3a, 3b, 4a, 4b respectively) with lithium dimethylcuprate and with sodium dimethylmalonate were examined.Regiospecific nucleophilic attack was observed in cases where the directing effects of the two substituents were matched.The reaction of 4a with sodium dimethyl methylmalonate was examined, and the product was subsequently transformed into a mixture of epi-lasiol and lasiol, a terpene with a novel rearranged skeleton.Key words: (Pentadienyl)Fe(CO)3 cations; C-C bond formation; terpene synthesis

A new, biogenetically anomalous, acyclic monoterpenol has been found in the mandibular glands of the formicine ant Lasius meridionalis, and identified as erythro-1, 2,3,6-trimethyl-5-heptenol (lasiol) on the basis of spectroscopic evidence and total synthesis.
