Abstract

ία μέθοδος διά την παρασκευήν της προγεστερόνης, εις την οποία η 3α-διυδροξυ-πρεγκνάνο-20-όνη ήτις εχει τον τύπον Ι, οξειδούται παρουσία νικελίου, πρός τον σκοπόν απολήψεως ως ενδιαμέσου προιόντος, του 6α-υδροξο-20-δικετοπαραγώγου έχοντος τον τύπο ΙΙ, το οποίον εν συνεχεία μετατρέπεται εις τον αντίστοιχον εστέρα ΙΙΙ του κ-τολυενοσουλφονικού οξέος,εκ του οποίου τέλος, διά κατεργασίας μετα οργανικών βάσεων εις θερμοκρασίαν κατωτέραν των 200 βαθμών κελσίου, γενικώς περίπου 150 σύν-πλήν 40 βαθμούςκελσίου, λαμβάνεται η προγεστερόνη IV. A process for the preparation of progesterone, in which 3α-dihydroxy-pregnanone-20-one is also of formula I, is oxidized in the presence of nickel, for the purpose of obtaining as intermediate, the 6α-hydroxy-20-benzene derivative having II, which is then converted to the corresponding ester III of n-tolyenesulfonic acid, from which, by treatment with organic bases at a temperature below 200 degrees Celsius, generally about 150 plus 40 degrees Celsius, progesterone IV is obtained.
