Stereoselective ammonium-directed epoxidation in the asymmetric syntheses of dihydroconduramines (–)-A-2, (–)-B-2, (–)-C-3 and (+)-F-3
Epoxidation of racemic trans -2-(N, N -dibenzylamino)cyclohex-3-en-1-ol, upon treatment with Cl 3 CCO 2 H then m -CPBA, proceeded with poor diastereoselectivity (ca. 60:40 dr), whilst epoxidation of racemic trans -2-(N -benzylamino)cyclohex-3-en-1-ol under the same conditions proceeded with high dia...
