The reduction of C(6)-acyl bicyclic tetramic acids has been achieved with complete diastereoselectivity via catalytic hydrogenation using PtO2. The resulting pyroglutamates had potent antibacterial and anticancer properties and will allow the preparation of simple mimics of pyroglutamate-containing natural products.

The synthesis and evaluation of 3-enaminetetramic acids as antibacterial agents is reported; contrary to the analogous 3-acyltetramic acids, the enaminetetramic acid class of compound exhibits modest antibacterial activityagainst a limited spectrum of organisms, and even that activity is strongly dependent on the identity of the tetramate ring substituents. Moreover, these compounds appear to have
