34% | General procedure: Following the procedures of Stork,15 the cycloketone and pyrrolidine (1.1equiv) were dissolved in benzene or toluene (300mLmol-1 ketone; toluene for n>1) and refluxed for 5-10h (cyclopentanone and -hexanone) or 24-48h (cycloheptanone and -octanone). Excess pyrrolidine and solvent were removed under reduced pressure and the yellow to brown oily residue was directly used for further reactions. For medium-sized rings a small amount of p-toluenesulfonic acid was added (n>1). (0024) Next, the enamine (typically 5-20g) was dissolved in anhydrous dioxane (400mLmol-1) under an argon atmosphere. Then the electrophile (1.5equiv; chloroacetonitrile for compounds 1, 3, 5 and 7, or acrylonitrile for compounds 2, 4, 6 and 8) was added in one shot using a syringe. Occasionally, more electrophile was added in case of stagnant reactions. The mixture was refluxed for 10-48h until complete conversion of the enamine could be detected by GC-MS. Subsequently, water (200mLmol-1) was added and the biphasic mixture was heated to reflux for 30-60min. Dioxane was then removed by rotary evaporation and the residue was partitioned between EtOAc (2mLmmol-1) and 2N HCl (0.5mLmmol-1). The aqueous phase was extracted with EtOAc (4× same volume as before) and the pooled extracts were dried over sodium sulfate and concentrated under reduced pressure. Purification of the brown crude oils was performed on MPLC or via distillation. |
