Stereoselective Synthesis of [3.3.0]‐Fused γ‐Butyrolactones of Carbohydrates
摘要:
A facile and stereoselective method is described for the preparation of fused 2,3-gamma-butyrolactones of lyxofuranose from the unexpected rearrangement in basic media of the photocycloadduct between homochiral 2(5H)-furanones and vinylene carbonate.
