| titleOfInvention | Process for the production of 3-hydroxy compounds |
| abstract | Process for the production of 7β-substituted 3-hydroxycepham-4-carboxylic acid compounds of the formula ##STR1## in which R 1 a represents hydrogen or an amino-protecting group R 1 A , and n R 1 b represents hydrogen or an acyl radical Ac, n or in which n R 1 a and R 1 b together form a bivalent amino-protecting group, and n R 2 represents a radical that, together with the carbonyl grouping --C(═O)--, forms a protected carboxyl group, n and 1-oxides thereof as well as salts of such compounds with salt-forming groups, from a 7β-substituted 3-hydroxy-3-cephem-4-carboxylic acid compound of the formula ##STR2## from a 1-oxide or a salt thereof, and a complex borohydride, characterized in that the reduction is carried out in the presence of an organic acid. n The reduction in the presence of an organic acid produces higher yields. |
