| 英文摘要 | reactions of o-ethyl lactim similar to(ch2)(3)-n=c(oet)similar to with 1-alkynyl fischer carbene complexes (oc)(5)m=c(oet)c equivalent to cph (m = cr, w) afforded biscarbene complexes with an azabicyclo[3.2.0]heptene core. under a nitrogen atmosphere, the resultant chromium biscarbene complex gave a sio2-promoted rearrangement complex in 86% yield. thermal annelation of the rearrangement product followed by hydrolysis over sio2 formed a cyclopentenone derivative. a cyclopentadiene derivative was obtained as a rare example of intermediate fischer carbene species, suggesting a possible reaction pathway for the thermal annelation of the rearrangement complex. stepwise oxidation of the chromium biscarbene complexes with an azabicyclo[3.2.0]heptene core with pyridine-n-oxide (pno) under mild controlled conditions generated partially and completely demetalated carbonyl products, respectively. the key carbene complexes and demetalated compounds were structurally characterized by x-ray crystallographic studies.
