REDUCTION OF ALLENIC ALCOHOLS BY SACCHAROMYCES CEREVISIAE
Gil, Gerard,Ferre, Elisee,Barre, Michael,le Petit, Jean
, p. 3797 - 3798 (1988)
α-Allenic alcohols are reduced by Saccharomyces cerevisiae into the corresponding β-ethylenic alcohols, whereas β-allenic alcohols undergo an isomerization leading to their γ-acetylenic counterparts.
Tertiary Amine Promoted Aziridination: Preparation of NH-Aziridines from Aliphatic α,β-Unsaturated Ketones

trans-NH-Aziridines were prepared from aliphatic α,β-unsaturated ketones using a tertiary amine promoted reaction via in situ generated N,N-ylides. Through use of modified conditions the reaction proved to be applicable for the diastereoselective aziridination of a range of enolisable aliphatic α,β-unsaturated ketones of varying substitution patterns.
Morpholinium trifluoroacetate-catalyzed aldol condensation of acetone with both aromatic and aliphatic aldehydes
Zumbansen, Kristina,Doehring, Arno,List, Benjamin
experimental part, p. 1135 - 1136 (2010/09/05)
We report a highly efficient, general and practical method for the aldol condensation of acetone with aromatic and aliphatic aldehydes, using morpholinium trifluoroacetate as a catalyst.
Synthesis of mono- and polycyclic tricarbonyliron cyclohexa-2,4-dienone complexes and phenols from tosylhydrazones of acyclic dienone complexes
Franck-Neumann, Michel,Geoffroy, Philippe,Gassmann, Dominique
, p. 2054 - 2058 (2007/10/03)
Cyclohexa-2,4-dienones stabilized by coordination to tricarbonyliron are obtained when the tosylhydrazones of tricarbonyliron-complexed α-dienones are thermolyzed in the presence of strong bases. This cyclocarbonylation reaction of carbenic intermediates is fairly general and can be used to synthesize various mono and polycyclic cyclohexadienone complexes or their decomplexed phenolic tautomers, and among them a new salicylate in the phenanthrene series.
A straightforward oxidation of dienones to 2-acetylfurans by selenium dioxide
No, Zaesung,Chae, Yung Bog,Shin, Chan Jae,Chung, Yongseog
, p. 6191 - 6194 (2007/10/03)
Direct oxidation of (E)-4-(6-substituted-1-cyclohexenyl)-3-buten-2-ones (4a-7a) by selenium dioxide afforded 2-acelyltetrahydrobenzofurans (4b-7b) in moderate to good yields. An inverse, stepwise [2+4] cycloaddition mechanism of the intermediate formation was proposed from conformational and electronic requirements of conjugated dienones and solvent effects of SeO2 oxidation.
Chemistry and structure-activity relationships of C-17 unsaturated 18-cycloalkyl and cycloalkyl analogues of enisoprost. Identification of a promising new antiulcer prostaglandin
Collins,Gasiecki,Perkins,Gullikson,Bianchi,Kramer,Ng,Yonan,Swenton,Jones,Bauer
, p. 2784 - 2793 (2007/10/02)
A series of Δ17 unsaturated cycloalkyl and cycloalkenyl analogues of enisoprost was synthetized to investigate the effects of ω chain unsaturation on gastric antisecretory activity and diarrheogenic side effects. Of these, the 17E, 18-cyclopent
13C NMR OF CARBONYL COMPOUNDS -4. SOLUTION CONFORMATION OF β-IONONE AND RELATED DIENONES
Muellen, K.,Schmickler, H.,Frei, B.,Wolf, H. R.
, p. 477 - 480 (2007/10/02)
The steric factors relevant for the conformations of β-ionone and structurally related compounds were studied by dynamic n.m.r. and 1H,1H-NOE measurements.
ACID CATALIZED RING CLOSURE REACTINOS OF ELECTROPHILIC ALKENES
Verhe, Roland,Kimpe, Norbert De,Courtheyn, Dirk,Buyck, Laurent De,Schamp, Niceas
, p. 3649 - 3660 (2007/10/02)
Treatment of α-acyl-α,β-unsaturated ketones with sulfuric acid or dimethylformamide-hydrogen chloride or p-toluenesulfonic acid gave rise to 3-acyl-2-alkyl-4,5-dihydrofurans.Similar cyclization of α-acyl-α,β-unsaturated esters initially afforded 3-alkoxycarbonyl-2-alkyl-4,5-dihydrofurans which were transformed into 2-acylbutanolides on further reaction with sulfuric acid.This acid catalized cyclization is strongly dependent upon the substitution pattern of the electrophilic alkenes, the acid used and reaction conditions.
