摘要
Ring contraction by BF3 ·Et2O catalyzed epoxide rearrangement of 3-substituted 5-trimethylsilyl-2,3-epoxycyclohexanones gave the corresponding 2-substituted 4-(trimethylsilyl)cyclopentanones diastereoselectively. Synthesis of (-)-massoialactone and (+)-β-cuparenone utilizing the above transformation is also described. © 1990.
