실험 절차

A 10 mL reaction vessel was charged with compound 245 (100 mg, 369 mmol), compound 281 (126 mg, 369 mmol), tris(dibenzylideneacetone)dipalladium (0) (25.3 mg, 27.6 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (32.0 mg, 55.3 mmol), sodium t-butoxide (70.8 mg, 737 mmol), and dioxane (1.5 mL).). The reaction was purged with argon and heated with microwave energy (300 W) for 2 hours at 120° C. The resulting solution was added to ethyl acetate (40 mL) and washed with water (30 mL) and brine (30 mL). The organic phase was dried (MgSO4) and evaporated to give an orange oil. Silica gel chromatography (gradient elution hexanes+2.5% TEA/0-35% ethyl acetate+2.5% TEA) afforded compound 282 as a yellow solid (121 mg, 57%).
