technique for the regioselective hydroboration and hydrosilylation of dehydroalaninederivatives has been developed. This method introduces synthetically versatile boron and silicon groups, while simultaneously performing a catalytic anti-Markovnikov hydrofunctionalization of dehydroalanines and dehydropeptides for the synthesis of amino acids and peptides bearing unnatural side-chains. The products obtained
A short protocol for the practical scale synthesis of several Ï-borono-α-amino acids is described via the alkylation of benzophenone glycinimines with various electrophiles.
