The nucleophilic cyclopropanation of hexa-1,5-diene-3,4-diones with bis(iodozincio)methane afforded the Zn alkoxides of cis-dialkenylcyclopropane-1,2-diols stereoselectively. The subsequent oxy-Cope rearrangement afforded the corresponding Zn alkoxides of
N-heterocyclic carbene catalyzed reaction of cinnamils leading to the formation of 2,3,8-triaryl vinyl fulvenes: An uncommon transformation

An unexpected transformation of 1,6-diarylhexa-1,5-diene-3,4-diones (cinnamils) to 2,3,8-triaryl vinyl fulvenes via N-Heterocyclic Carbene (NHC) catalysis is reported. Mechanistic as well as synthetic novelty is the hallmark of this reaction.

supporting information; experimental part, p. 5204 - 5205 (2011/02/23)
Treatment of 1,6-dialkylhexa-1,5-diene-3,4-diones with bis(iodozincio) methane gave zinc alkoxides of cis-5,6-dialkylcyclohepta-3,7-diene-1,3-diol in good yields at room temperature. The reaction proceeded with high stereospecificity. Bis(iodozincio)metha
Enantioselective, cyclopentene-forming annulations via NHC-catalyzed benzoin-oxy-Cope reactions

Chiral N-heterocyclic carbene catalysts generated from triazolium salts promote the cyclopentene-forming annulation of α,β-unsaturated aldehydes and 4-oxoenoates with excellent levels of enantioinduction and preference for the cis-1,3,4-trisubstituted cyclopentene diastereomer. Although the observed products could arise by conjugate additions of catalytically generated homoenolates, our mechanistic and stereochemical investigations strongly support a novel reaction manifold featuring an intermolecular crossed-benzoin reaction and an NHC-catalyzed oxy-Cope rearrangement.

Electroreductive coupling of aromatic acyl bromides to 1,2-diketones
Kise,Ueda
, p. 755 - 756 (2007/10/03)
The direct electroreduction of aromatic acyl bromides gave aromatic 1,2-diketones. The best result was obtained using a Pb cathode in acetonitrile containing Bu4NClO4 as a supporting electrolyte. Aromatic acyl bromides substituted by an electron-donating group afforded 1,2-diketones in moderate-to-good yields, whereas acylated endiols were formed exclusively from aromatic acyl bromides substituted by an electron-withdrawing group.
Cinnamil - An Oligopyridine Precursor
Constable, Edwin C.,Hannon, Michael J.,Smith, Diane R.
, p. 6657 - 6660 (2007/10/02)
A new methodology has been employed to synthesize a quaterpyridine, a sexipyridine and a quaterpyridine analogue in which the central 2,2'-bipyridine units is derived from cinnamil.
