摘要:
DESA-9B-STEROIDS ARE PRODUCED BY THE HYDROGENATION OF DESA->9 STEROIDS USING A PALLIDIUM CATALYST IN THE PRESENCE OF HYDROBRONIC ACID. THESE COMPOUNDS ARE USEFUL INTERMEDIATES FOR THE PREPARATION OF HORMONALLY ACTIVE 9B,10ASTEROIDS.
摘要:
BENZ(E)INDENE DERIVATIVES AND INTERMEDIATES THEREFOR HAVE BEEN PREPARED BY VARIOUS PROCESSES STARTING FROM HEXAHYDROINDANE DERIVATIVES. THE BENZ(E)INDENE END PRODUCTS BELONG TO A KNOWN CLASS OF COMPOUNDS AND ARE USEFUL AS INTERMEDIATES IN THE SYNTHESIS OF STEROIDAL COMPOUNDS.
摘要:
The present invention relates to a microbiological method for producing 20beta-hydroxy-9-oxo-1,2,3,4,10,19-hexanor-5,9-secopregnan-5-oic acid, an intermediate for known steroids, from 3beta, 20beta-dihydroxypregn-5-ene or 2beta, 20-dihydroxypregn-5ene.
