Chen, Yi-Hung,Tüllmann, Carl Phillip,Ellwart, Mario,Knochel, Paul
, p. 9236 - 9239 (2017)
We report the preparation of solid and air-stable polyfunctionalized alkynylzinc pivalates from the corresponding alkynes using TMPZnOPiv (TMP=2,2,6,6-tetramethylpiperidyl) as base. These organozinc pivalates are obtained as powders under mild conditions

In recent years, channels that mediate store-operated calcium entry (SOCE, i.e., the ability of cells to sense a decrease in endoplasmic reticulum luminal calcium and induce calcium entry across the plasma membrane) have been associated with a number of d
Cobalt(II)-based Metalloradical Activation of 2-(Diazomethyl)pyridines for Radical Transannulation and Cyclopropanation

A new catalytic method for the denitrogenative transannulation/cyclopropanation of in-situ-generated 2-(diazomethyl)pyridines is described using a cobalt-catalyzed radical-activation mechanism. The method takes advantage of the inherent properties of a CoIII-carbene radical intermediate and is the first report of denitrogenative transannulation/cyclopropanation by a radical-activation mechanism, which is supported by various control experiments. The synthetic benefits of the metalloradical approach are showcased with a short total synthesis of (±)-monomorine.

Paragraph 000508; 000509, (2018/01/17)
Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with the enzyme ceramide galactosyltransferase (CGT), such as, for example, lysosomal storage diseases. Examples of lysosomal storage diseases include, for example, Krabbe disease and Metachromatic Leukodystrophy.
Aryl Nitriles from Alkynes Using tert -Butyl Nitrite: Metal-Free Approach to C≡C Bond Cleavage

Alkyne C≡C bond breaking, outside of alkyne metathesis, remains an underdeveloped area in reaction discovery. Recently, nitrogenation has been reported to allow nitrile formation from alkynes. A new protocol for the metal-free C≡C bond cleavage of terminal alkynes to produce nitriles is reported. This method provides an opportunity to synthesize a vast range of nitriles containing aryl, heteroaryl, and natural product derivatives (38 examples). In addition, the potential of tBuONO to act as a powerful nitrogenating agent for terminal aryl alkynes is demonstrated. (Figure Presented).
SUBSTITUTED PHENYLACETYLENES, PHARMACEUTICAL COMPOSITIONS CONTAINING THESE COMPOUNDS AND PROCESSES FOR THE PREPARATION OF THESE COMPOUNDS AND COMPOSITIONS

, (2008/06/13)
Substituted phenylacetylenes of the formula STR1 wherein one of the groups R1 is a hydrogen atom and the other represents the group of the formula STR2 in which R3 is hydrogen, methyl or ethyl and R4 is a methyl or an amino group and wherein R2 represents mono- or binuclear aromatic or heterocyclic residues containing sulfur, nitrogen or oxygen as hetero atoms and optionally being substituted by 1 to 3 substituents as defined, which specifically inhibit 5-lipoxygenase and are useful in pharmaceutical compositions for prophylaxis and treatment of diseases due to the action of leukotrienes. The compounds may be prepared by reacting a compound of the formula STR3 wherein R2 has the same meaning as above and one of the groups R7 is a hydrogen atom and the other represents the group of the formula --COR3, with hydroxylamine to form the oxime which then is reduced to the corresponding hydroxylamine compound into which the group of the formula --COR4 is introduced.
