General description

Palladium-catalyzed cross-coupling reaction of tert-butyl carbamate with various aryl(Het) halides with Cs2CO3 as base in 1,4-dioxane (solvent) has been investigated.

Application

tert-Butyl carbamate was used in palladium-catalyzed synthesis of N-Boc-protected anilines. It was used in the synthesis of tetrasubstituted pyrroles, functionalized with ester or ketone groups at C-3 position.
