1-(thiophen-2-yl)ethanamine), and aminoacid esters containing a benzylamine moiety, are highly efficient substrates, and their chirality is efficiently transferred to the products (94–99% ee). The absolute configurations of the products are predictable and follow the pattern of SN2-type substitutions; an inversion of the absolute configuration of the tertiary amines occurs during the C–S coupling reaction.
