Procedure: 4-Pentenoyl chloride (8.16 g, 69.1 mmol) was added dropwise to sodium phenoxide (8.02 g, 69.1 mmol) in THF (160 ml) at 20° C. After 24 hours at 20° C. H2O (100 ml) was added and the aqueous phase was extracted with Et2O (3×200 ml). The organic phase was washed with NaHCO3 (2×200 ml), brine (2×200 ml) to neutrality, then dried (Na2SO4), filtered, concentrated and bulb-to-bulb distilled to afford the desired title ester in 90% yield. B.p.: 70° C./0.04 mbar. the aqueous phase was extracted with Et2O (3×200 ml) The organic phase was washed with NaHCO3 (2×200 ml), brine (2×200 ml) to neutrality dried (Na2SO4) filtered concentrated bulb-to-bulb distilled

Procedure: A 250-mL round-bottom flask equipped with a stir bar was charged with 4-pentenoic acid (5.10 mL, 50.0 mmol) and CH2Cl2 (40 mL), followed by thionyl chloride (4.00 mL, 55.0 mmol). The mixture was allowed to stir for 30 min, at which point phenol (9.45 g, 100 mmol) was added as a solution in CH2Cl2 (10 mL). The mixture was allowed to cool to 0° C. (ice-bath), and triethylamine (28 mL, 200 mmol) was added dropwise by a syringe over 5 min (N.B., strong exotherm). The resulting solution was allowed to stir for 12 h at 22° C. The reaction was quenched by addition of a saturated aqueous solution of NaHCO3 (100 mL). The organic layer was separated, and the aqueous layer washed with CH2Cl2 (5×50 mL). The combined organic layers were washed with water (1×50 mL), brine (1×50 mL), dried over MgSO4, filtered, and concentrated in vacuo. The resulting oil was purified by silica gel chromatography (95:5 hexanes:EtOAc) to deliver a colorless oil. The oil was distilled from CaH2 under reduced pressure (1.0 torr) to afford phenyl(4-pentenoate) (2.58 g, 14.6 mmol, 29.0% yield) as a colorless oil. Spectral data matched those in the literature.

Procedure: Following the general procedure, phenyl pent-4-enoate (50.0 mg, 0.284 mmol) was treated with butyl vinyl ether (284 mg, 2.84 mmol) and 2.5 mol % of in situ-generated complex la (71.0 μL, 0.10 M, 7.09 μmol; final substrate concentration=4.0 M) and allowed to stir for 2 h. The unpurified product is 98% Z (as determined by 400 MHz 1H NMR analysis). The resulting oil was purified by silica gel chromatography (50:1 hexanes:Et2O) to afford 8c (55.6 mg, 0.224 mmol, 79.0% yield, >98% Z isomer) as a colorless oil.
