  An Unexpected Oxidation in the Generation of Cyclopenta[c]piperidines by Ring-Closing Metathesis

  摘要：

  Ring-closing metathesis reaction of dienes A (n = 1, R = CO2R') leads to fused cyclopentenones C instead of the expected cyclopentene derivatives B. RCM reaction of the other dienes A takes place satisfactorily, affording the expected fused cycloalkene derivatives B. Cyclohexene B (n = 2, R = CO2R') also undergoes oxidation to the corresponding cyclohexenone C.
