Summary of "-PrNMgCl·LiCl Enables the Synthesis of Ketones by Direct Addition of Grignard Reagents to Carboxylate Anions."

The direct preparation of ketones from carboxylate anions is greatly limited by the required use of organolithium reagents or activated acyl sources that need to be independently prepared. Herein, a specific magnesium amide additive is used to activate and control the addition of more tolerant Grignard reagents to carboxylate anions. This strategy enables the modular synthesis of ketones from CO and the preparation of isotopically labeled pharmaceutical building blocks in a single operation.

Chemo-Selective Synthesis of Aryl Ketones from Amides and Grignard Reagents via C(O)-N Bond Cleavage Under Catalyst-free Condition.

Conversion of a wide range of N-Boc amides into aryl ketones was achieved with Grignard reagents via chemoselective C(O)-N bond cleavage. The reactions proceeded under catalyst-free condition with dif...

Desymmetrisation reactions of indigo with Grignard reagents for the synthesis of selective antiplasmodial 1,3ꞌ-3-aryl-2,2ꞌ-diindol-3ꞌ-ones.

The nucleophilic addition of organomagnesium and organolithium species to the cheap and robust natural dye indigo led to desymmetrisation of the heterocyclic nucleus via a Grignard addition-dehydratio...

Regiodivergent and Stereospecific Aziridine Opening by Copper-Catalyzed Addition of Silicon Grignard Reagents.

A stereospecific ring opening of various 2-aryl-substituted aziridines with silicon Grignard reagents under copper catalysis is reported. The regiochemical outcome is governed by the steric demand of ...

Tandem Acyl Substitution/Michael Addition of Thioesters with Vinylmagnesium Bromide.

A tandem reaction of thioesters with vinylmagnesium bromide is reported. The initial acyl substitution provides an α,β-unsaturated ketone which further reacts with the liberated thiolate. This trans...

Medical and Biotech [MESH] Definitions

A noninvasive diagnostic technique that enables an experienced clinician to perform direct microscopic examination of the surface and architecture of pigmented SKIN lesions. The four major dermoscopic criteria are ABCD: asymmetry (A), borders (B), colors (C), and different structural components (D) providing a semiquantitative scoring system for each lesion.

Sequences found near the 3' end of MESSENGER RNA that direct the cleavage and addition of multiple ADENINE NUCLEOTIDES to the 3' end of mRNA.

The process in which structural properties of an introduced molecule imitate or simulate molecules of the host. Direct mimicry of a molecule enables a viral protein to bind directly to a normal substrate as a substitute for the homologous normal ligand. Immunologic molecular mimicry generally refers to what can be described as antigenic mimicry and is defined by the properties of ANTIBODIES raised against various facets of EPITOPES on the viral protein. (From Immunology Letters 1991 May;28(2):91-9)

A transmembrane domain-containing matrix metalloproteinase. It is synthesized as an inactive zymogen that is activated by the action of PROPROTEIN CONVERTASES such as FURIN. Matrix metalloproteinase 14 plays a direct role in the cleavage of proteins in the pericellular environment. In addition it can function indirectly by enzymatically activating the proprotein form of MATRIX METALLOPROTEINASE 15.

One of several basic proteins released from EOSINOPHIL cytoplasmic granules. Eosinophil major basic protein is a 14-kDa cytotoxic peptide with a pI of 10.9. In addition to its direct cytotoxic effects, it stimulates the release of variety of INFLAMMATION MEDIATORS.
