Control of stereochemistry is achieved using two TentaGel-bound di-tert-butoxyprotected hydroxyprolyl-threonine catalysts (see picture, sphere represents TentaGel). These catalysts mediate asymmetric tandem enamine/Michael reactions with high enantioselectivity and complete diastereoselectivity; the choice of catalyst depends on the desired absolute configuration.
