Procedure
A 1000 mL three necked round bottomed flask outfitted with a mechanical stirrer (Teflon paddle), a pressure equalizing addition funnel was charged with pentaerythritol triallyl ether (NEOALLYL P-30) (111.9 g, 436.5 mmol), toluene (300 mL) and triethylamine (56.61 g, 559.4 mmol). The addition funnel was charged with a solution of BCB-AA acid chloride (88.96 g, 461.8 mmol) from Example 6 in toluene (100 mL), which was then added dropwise to the reaction mixture over 45 min. The solution was then heated to 90° C. for 9.5 hr. The solution was then filtered through a 38 mm (1.5 inch) thick silica gel plug on a 350 mL fritted glass funnel. Hexane:ethyl acetate (80:20, 200 mL) was used as the washing solvent. The filtrate was condensed to afford an orange colored viscous oil, which was taken up in hexanes (300 mL) and placed into a freezer for 3 days. The solution was filtered and condensed to afford the product as a viscous dark yellow colored oil. Yield: 178.0 g (93.97%). 1H NMR (500 MHz, Chloroform-d) δ 7.67 (dd, J=15.9, 3.1 Hz, 1H), 7.36 (dd, J=7.6, 1.5 Hz, 1H), 7.31-7.18 (m, 1H), 7.13-6.94 (m, 1H), 6.39 (d, J=16.0 Hz, 1H), 5.97-5.78 (m, 2H), 5.27 (dd, J=17.3, 1.7 Hz, 2H), 5.15 (dd, J=10.5, 1.6 Hz, 2H), 4.30 (s, 2H), 3.97 (d, J=5.4 Hz, 4H), 3.52 (s, 4H), 3.20 (s, 3H).
