General methods All reactions were carried out in dry glassware under an argon atmosphere using standard Schlenk techniques or in a Vacuum Atmospheres Glovebox under a nitrogen atmosphere, unless otherwise specified. All solvents were purified by passage through solvent purification columns and further degassed by bubbling argon. NMR solvents were dried over CaH 2 and vacuum transferred to a dry Schlenk flask and subsequently degassed with bubbling argon. C 6 D 6 was purified by passage through a solvent purification column. CDCl 3 was used as received. All α-olefins were filtered through a plug of neutral alumina prior to use. Ruthenium complex 1 was obtained from Materia Inc. 11-eiosenol (4) was synthesized from Jojoba oil. 1 Other commercially available reagents and silica gel were used as received. 1 H NMR spectra were acquired at 500 MHz and 13 C NMR spectra at 125 MHz as CDCl 3 solutions unless otherwise noted. Quantitative 13 C measurements were acquired at 100 MHz (decoupled, without NOE, 15 second delay time). High-resolution mass spectra (HRMS) were provided by the California Institute of Technology Mass Spectrometry Facility using a JEOL JMS-600H High Resolution Mass Spectrometer. All HRMS were by positive-ion EI or FAB. All cross metathesis reactions involving the seed oil derivatives 2 and 4 required purification by multiple columns to separate the desired products from the starting material and any terminal olefins generated. 1 R.L.
