Abstract

1510195 Reduction process LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT 16 June 1975 25541/75 Heading C2C [Also in Division B1] Oxytetracycline, quinolysine and steroid derivatives are stereospecifically reduced, (e.g. 6 - deoxy - 6 - demethyl - 6 - methylene - 5- oxytetracycline is reduced to α-6-deoxy-5- oxytetracycline) and acid chlorides are selectively reduced to aldehydes (e.g. trimethoxybenzaldehyde, salicylaldehyde and γ - chlorobutyraldehyde are obtained from the corresponding acid chlorides) in the presence of catalysts comprising a platinum group metal and a group IB and/or group IIB metal component formed by simultaneous deposition of salts, complexes and/or hydroxides of the metals on a support, reduction at 0-100‹ C., multiple washing with water and, optionally, drying.
