A number of orally active cephalosporins and penicillins with interesting biological activity were synthesized. Two of these, 7-[[[3,4-(methylenedioxy)phenyl]glycyl]amino]deacetoxycephalosporanic acid and 7-[[2-(2,3-dihydro-5-benzofuranyl)glycyl]amino]deacetoxycephalosporanic acid were considerably more active than cephalexin both in vitro and in vivo against staphylococcal and streptococcal infections.

The present invention relates to compounds of the formula
which are useful in treating diseases characterized by the hyperactivity of MEK. Accordingly the compounds are useful in the treatment of diseases, such as, cancer, cognative and CNS disorders and inflammatory/autoimmune diseases.
cathode and an Mg rod anode under atmospheric pressure of bubbling carbondioxide through the solution under constant current conditions resulted in a reductive C–S bond cleavage with elimination of benzenesulfinate ion generating the corresponding anion species followed by fixation of carbondioxide to give the corresponding N-Boc-α-amino acids in moderate to good yields.
