Abstract
A highly selective combination of ruthenium complex and oxidant, which catalyzes the oxidative C–H esterification of allylarenes to the corresponding bis-(E)-cinnamates and (E)-cinnamates, is described. The one-pot route was carried out by olefinic migration of allylarenes with RuCl2(PPh3)3 and DDQ-mediated allylic oxidation of the resulting internal alkenes with various alcohols in good yields.

- 13 Representative Synthetic Procedure of Skeletons 3, 8, and 10 RuCl2(PPh3)3 (38 mg, 0.04 mmol) was added to a solution of skeleton 2, 7, or 9 (0.4 mmol) in CH2Cl2 (10 mL) at reflux for 2 h. The reaction mixture was cooled to r.t. Then alcohols (1 mL) and DDQ (for skeleton 2: 900 mg, 4.0 mmol; for skeleton 7 or 9: 450 mg, 2.0 mmol) were added to the reaction mixture. The reaction mixture was stirred at reflux for 1 h. The reaction mixture was cooled to r.t. The residue was diluted with H2O (10 mL), and the mixture was extracted with CH2Cl2 (3 × 20 mL). The combined organic layers were washed with brine, dried, filtered, and evaporated to afford crude product. Purification on silica gel (hexanes–EtOAc = 10:1 to 6:1) afforded skeletons 3, 8, and 10.
