Abstract

Based upon the recent developments in enantioselective Heck-Matsuda arylations, it is proposed herein the use of a substrate oriented methodology in order to achieve not only enantioselectivity but also regioselectivity at cyclic olefins desymmetrization. To carry out this transformation it is proposed uncommon intermediates such as a (valence saturated) pentacoordinated cationic PdII specie. Experimental conditions must be optimized, and several olefins containing different directing groups shall be synthesized and finally evaluated in the developed methodologyThrough this proposal highly functionalized building blocks as arylated allylic alcohols possessing two stereogenic centers are going to be reachable in a straight manner. Those units are present in a variety of biologically active compounds.
