Reaktionsschritte

To a sealed tube containing 96.A (0.2020 g, 0.455 mmol), bis(dibenzylideneacetone)palladium(0) (0.0141 g, 0.0245 mmol), and CTC-Q-Phos (0.0168 g, 0.0236 mmol) was added dry THF (3 mL). After 5 minutes, 3-ethoxy-3-oxopropylzinc bromide (2.0 mL, 1.00 mmol) (0.5 M solution in THF) was added. After 1 hour, the mixture was heated to 80° C. and monitored with TLC and LC-MS. After 16.5 hours, the reaction was cooled to room temperature, and the organic solvent was removed under reduced pressure. The residue was purified by silica gel flash chromatography (0-40% EtOAc/hexane) to afford 96.B which was used without further purification (129.1 mg, 61% yield). MS ESI (pos.) m/e: 466.3 (M+H)+.
