unreactive in cross‐coupling reactions which mostly employ more electrophilic halides or activated esters (triflates, tosylates). Acetates are cheap and easily accessible electrophiles but have not been used in cross‐couplings because the strong CO bond and high propensity to engage in unwanted acetylation and deprotonation. Reported herein is a selective iron‐catalyzedcross‐coupling of diverse alkenyl
A series of η4-acyloxycyclohexadiene–Fe(CO)3 complexes was prepared and fully characterized by spectroscopic methods including single crystal X-ray diffraction. For this purpose a new synthetic access to differently acylated 1,3- and 1,5-dienol–Fe(CO)3 complexes was developed. The enzymatically triggered CO release from these compounds was monitored (detection of CO through GC and/or by means of a

3-Cyclopropanecarbonyloxy-2-cyclohexen-1-one has been found to be a new, potent, low molecular weight non-triketone type inhibitor of 4-hydroxyphenylpyruvatedioxygenase with IC50 value of 30 nM. Preliminary studies suggest that the two carbonyl groups present in the compound are crucial for the inhibition activity.
