Stereoselective Ring Expansion via Bicyclooxonium Ion. A Novel Approach to Oxocanes
摘要:
[GRAPHICS]The stereoselective 1,4-rearrangement-ring expansion of tetrahydrofurans via bicyclo[3.3.0]oxonium ions was developed to synthesize oxocanes. On the basis of this rearrangement, the stereoselective synthesis of 2,8-syn-2,8-dimethyloxocane was accomplished.
