Anionic versus photochemical diastereoselective deconjugation of diacetone D-glucose α,β-unsaturated esters
Bargiggia, Frederic,Piva, Olivier
, p. 1819 - 1827 (2003)
Deconjugation of diacetone D-glucose α,β-unsaturated esters has been conducted by deprotonation using NaHMDS with HMPA as co-solvent followed by stereoselective protonation at low temperature. High selectivities (>95%) were obtained with α-methyl linear compounds.

Peroxisome proliferator-activated receptor gamma (PPARγ) modulators have found wide application for the treatment of cancers, metabolic disorders and inflammatory diseases. Contrary to PPARγ agonists, PPARγ antagonists have been much less studied and alth
Macrolide Synthesis through Intramolecular Oxidative Cross-Coupling of Alkenes

supporting information, p. 555 - 559 (2018/02/21)
A RhIII-catalyzed intramolecular oxidative cross-coupling between double bonds for the synthesis of macrolides is described. Under the optimized reaction conditions, macrocycles containing a diene moiety can be formed in reasonable yields and with excellent chemo- and stereoselectivity. This method provides an efficient approach to synthesize macrocyclic compounds containing a 1,3-conjugated diene structure.

Paragraph 24, (2016/05/10)
The present invention pertains to a new compound E)-2-(5-((4-methoxy-2- (trifluoromethyl)quinolin-6-yl)methoxy)-2-((4-(trifluoromethyl) benzyl)oxy)-benzylidene) hexanoic acid (MTTB), and its derivatives. The compounds of the invention are useful as select
SAR-studies of γ-secretase modulators with PPARγ-agonistic and 5-lipoxygenase-inhibitory activity for Alzheimer's disease

We present the design, synthesis and biological evaluation of compounds containing a 2-(benzylidene)hexanoic acid scaffold as multi-target directed γ-secretase-modulators. Broad structural variations were undertaken to elucidate the structure-activity-relationships at the 5-position of the aromatic core. Compound 13 showed the most potent activity profile with IC50 values of 0.79 μM (Aβ42), 0.3 μM (5-lipoxygenase) and an EC50 value of 4.64 μM for PPARγ-activation. This derivative is the first compound exhibiting low micromolar to nanomolar activities for these three targets. Combining γ-secretase-modulation, PPARγ-agonism and inhibition of 5-lipoxygenase in one compound could be a novel disease-modifying multi-target-strategy for Alzheimer's disease to concurrently address the causative amyloid pathology and secondary pathologies like chronic brain inflammation.
Dialkylation of diethyl ethoxycarbonylmethylphosphonate under microwave and solventless conditions
Gruen, Alajos,Blastik, Zsofia,Drahos, Laszlo,Keglevich, Gyoergy
, p. 107 - 113 (2014/04/03)
To further broaden the methods for the heterogeneous phase alkylation of CH acidic compounds, the dialkylation of diethyl ethoxycarbonylmethylphosphonate was studied in the presence of Cs2CO3 under microwave and solvent-free conditio
Microwave-assisted alkylation of diethyl ethoxycarbonylmethylphosphonate under solventless conditions
Gruen, Alajos,Blastik, Zsofia,Drahos, Laszlo,Keglevich, Gyoergy
experimental part, p. 241 - 246 (2012/07/28)
The reaction of diethyl ethoxycarbonylmethylphosphonate with a series of alkyl halides, under microwave (MW) and solventless conditions at 120°C, in the presence of Cs2CO3 and in the absence of a phase transfer catalyst afforded the corresponding monoalkylated products in yields of >70%. The thermal variant carried out in boiling acetonitrile was slow and led to incomplete conversions. In the MW method, the phase transfer catalyst is substituted by MW irradiation and there is no need for a solvent.
