active esters, which have been successfully used in simple Ni- catalyzed cross-coupling reactions, [7] and to take advantage of the presence of an alkene to realize a cyclization,

Sequential C −H Arylation and Carbonylative Cyclization for Introducing Structural Diversity and Complexity on tert-Leucine Derivative (+)-1. a Monoarylation conditions: AgOAc

Moreover, the enallene 70 used by Bäckvall and coworkers, 241f was also subjected to the reaction conditions giving rise to a mixture of three alkylboronates (71) located around

Ammonium salts with aryl and silyl substitution on the alkyne and different alkyl chains at the propargylic position afford- ed the desired compounds in high yield and

cycloaddition directly promoted by the substrate-catalyst complex species to access a family of cyclic β-aminocarbonyl derivatives.. The investigation began by selecting

In the second chapter of this Doctoral Thesis we have developed a stereospecific copper-catalyzed substitution reaction of propargylic ammonium salts with

It was not until 2005, when Sawamura reported the copper-catalyzed borylation of allylic carbonates, that the synthetic potential of copper- catalyzed

The influence of acidic and alkaline additives was studied on the Pd/C-catalyzed reductive processing of poplar wood in methanol: under acidic (H 3 PO 4 ) conditions
