Discovery of N-(3,4-Dimethylphenyl)-4-(4-isobutyrylphenyl)-2,3,3a,4,5,9b-hexahydrofuro[3,2-c]quinoline-8-sulfonamide as a Potent Dual MDM2/XIAP Inhibitor
Pentamethylcyclopentadienide in organic synthesis: nucleophilic addition of lithium pentamethylcyclopentadienide to carbonyl compounds and carbon–carbon bond cleavage of the adducts yielding the parent carbonyl compounds
dienide (C5Me5Li, Cp*Li) reacted with aromatic aldehyde to provide the corresponding carbinol in excellent yield. The carbinol returns to the parent aldehyde and pentamethylcyclopentadiene upon exposure to acid or due to heating. Chlorodimethylaluminum is essential as an additive to attain the nucleophilic addition of Cp*Li to aliphatic aldehyde. The carbinol derived from aliphatic aldehyde returns
五甲基环戊二烯化锂(C 5 Me 5 Li,Cp * Li)与芳族醛反应以优异的产率提供相应的甲醇。甲醇在暴露于酸中或加热后会返回为母体醛和五甲基环戊二烯。氯二甲基铝对于实现Cp * Li向脂肪族醛的亲核加成反应至关重要。衍生自脂族醛的甲醇在催化量的2,3-二氯-5,6-二氰基苯并醌(DDQ)的作用下返回母体醛和五甲基环戊二烯。Cp *基团的可逆加成/消除可表示对醛的保护。还公开了碳-碳键裂解的机理细节。

Provided herein are compounds, pharmaceutical compositions including such compounds, and methods of using such compounds to treat diseases or disorders associated with MDM2 activity.
A direct transformation of secondary amides into α‐branched ketones with enamines as soft alkylation reagents was developed. In this reaction, enamines serve as surrogates of alkyl carbanions, rather than the conventional enolates equivalents in the Stork's reactions, which allowed for the easy introduction of alkyl groups with electrophilic functional groups. In the presence of 4 Å molecular sieves

A series of multicoordinating and multifunctional ligands optimized for the surface-functionalization of luminescent quantum dots (QDs) and gold nanoparticles (AuNPs) alike is disclosed. An L-aspartic acid precursor is modified with functionality, through simple peptide coupling chemistry, one or two lipoic acid (LA) groups and poly(ethylene glycol) (PEG) moieties in the same ligand. These ligands were combined with a new photoligation strategy to yield hydrophilic and reactive QDs that are colloidally stable over a broad range of conditions, including storage at nanomolar concentration and under ambient conditions.
The instant invention provides compounds of Formula I which are 5-lipoxygenase activating protein inhibitors: formula (I). Compounds of Formula I are useful as anti-atherosclerotic, anti-asthmatic, anti-allergic, anti-inflammatory and cytoprotective agents.
