实验过程

A solution of δ-damascone (10.0 g; 52.1 mmol) and 1-dodecanthiol (8.42 g, 41.7 mmol) in THF (150 ml) was treated with DBU (7.92 g; 52.1 mmol) and stirred at 45° C. for 90 min. The reaction solution was treated with 5% aqueous HCl, extracted twice with ether, washed with H2O, saturated aqueous NaHCO3, then brine, dried over Na2SO4, and concentrated at 70° C./0.01 mbar. Yield of crude product: 16.2 g (99%).
