Diastereoselective ammonium-directed epoxidation in the asymmetric syntheses of dihydroconduramines (+)-C-2, (−)-C-2, (+)-D-2, (+)-E-2, (+)-F-2, and (−)-F-2
Epoxidations (40% aq HBF4 then m-CPBA) of racemic cis-2-(N-benzylamino)cyclohex-3-en-1-ol and racemic cis-2-(N,N-dibenzylamino)cyclohex-3-en-1-ol proceed with very high levels of diastereoselectivity (>95:5 dr). The latter is in direct contrast to the epoxidation of the corresponding trans-di...
