The present thesis work dealt with the development on new palladium-catalyzed pseudo-domino sequences. A first pseudo-domino type I process featuring a carbonylation / decarboxylative allylation was designed with α-chloroacetophenone. The sequence allowed the selective monoallylation of readily available α-chloroketones derivatives in one single synthetic operation. This pseudo-domino sequence could be applied to variously substituted acetophenones. We also designed a three-step pseudo-domino reaction featuring N-allylation / carbopalladation / carbonylation. This sequence allowed us to prepare substituted indolines in one single synthetic operation from readily available substrates. The extension to a four step pseudo-domino sequence was also envisaged. Switching the alcohol used to allyl alcohol should merge both sequences, by adding a decarboxylative allylation step to the three-step process
