Nickel-catalyzed monofluoromethylation of aryl boronic acids

Aryl boronic acids can be monofluoromethylated under nickel catalysis. The utility of this method is demonstrated by the monofluoromethylation of a borylated and acyl-protected derivative of the statin drug ezetimibe. Mechanistic investigations indicate that a fluoromethyl radical is involved in the NiI/NiIII catalytic cycle.

Rhodium catalyzed C-C bond cleavage/coupling of 2-(azetidin-3-ylidene)acetates and analogs

The C-C bond cleavage/coupling of 2-(azetidin-3-ylidene)acetates with aryl boronic acids catalyzed by a rhodium complex was studied with a "conjugate addition/β-C cleavage/protonation" strategy.

Palladium-Catalyzed Chemoselective Negishi Cross-Coupling of Bis[(pinacolato)boryl]methylzinc Halides with Aryl (Pseudo)Halides

We describe a palladium-catalyzed chemoselective Negishi cross-coupling of a bis[(pinacolato)boryl]methylzinc halide with aryl (pseudo)halides. This reaction affords an array of benzylic 1,1-diboronate esters, which can serve as useful synthetic handles f

2-AZETIDINONES AS ANTI-HYPERCHOLESTEROLEMIC AGENTS

The instant invention provides novel cholesterol absorption inhibitors of Formula I and the pharmaceutically acceptable salts and esters thereof. The compounds are useful for lowering plasma cholesterol levels, particularly LDL cholesterol, and for treati

4-BIARYLYL-1-PHENYLAZETIDIN-2-ONES

4-Biarylyl-1-phenylazetidin-2-ones useful for the treatment of hypercholesterolemia are disclosed. The compounds are of a general formula (I) in which formula (II) represents an aryl or heteroaryl residue, Ar represents an aryl residue; U is a two to six atom chain; and the R’s represent substituents.
