Immobilized boronic acid for Suzuki–Miyaura coupling: application to the generation of pharmacologically relevant molecules

An efficient Suzuki–Miyaura coupling of immobilized boronic acid for the generation of a variety of biaryl biologically interesting derivatives is reported.

Chemoselective and Sequential Palladium-Catalyzed Couplings for the Generation of Stilbene Libraries via Immobilized Substrates

A versatile palladium-catalyzed tandem synthetic sequence to afford E-stilbenes libraries has been developed. Excellent regio- and stereocontrol have been achieved by means of the sequence of Hiyama and Heck cross-couplings. Undesirable homocoupling byproducts were avoided employing immobilized substrates.

Solid-supported cross-metathesis and a formal alkane metathesis for the generation of biologically relevant molecules

Solid-phase synthetic strategies toward the generation of libraries of biologically relevant molecules were developed using olefin cross-metathesis as a key step. It is remarkably the formal alkane metathesis based on a one-pot, microwave-assisted, ruthenium-catalyzed cross-metathesis and reduction to obtain Csp3-Csp3 linkages.

Palladium-catalyzed cross-coupling reactions of arylsiloxanes with aryl halides: application to solid-supported organic synthesis

The solid-phase version of the Pd-catalyzed Hiyama reaction between a variety of aryltriethoxysilanes and immobilized aryl halides was developed. Smooth cross-coupling was achieved to afford the corresponding biaryl products in moderate to excellent yields. The described protocol would be particularly useful for the construction of 4'-substituted 1,1'-biphenyl derivatives.
