English term or phrase: Allopregnatrione
Salve a tutti,
mi sono imbattuto in questo termine, del quale io e "google" ignoriamo l'esistenza.
Potrebbe trattarsi di un typo? Il problema è che è presente più volte nel testo, quindi mi sembra strano sia un typo..
Grazie per l'aiuto

The synthetic route involves these key steps:
Step 1.
Preparation of 11-ketoprogesterone (Intermediate 1)
Step 2.
Preparation of allopregnatrione (Intermediate 2)
Step 3.
Henbest Reduction to produce crude alfaxalone (Intermediate 3)
Step 4.
Acetylation of crude alfaxalone to form acetoxy alfaxalone (Intermediate 4)
Step 5.
Hydrolysis of acetoxy alfaxalone to form pure alfaxalone.
Step 6.
This final step involves drying the recrystallised product at 60 °C until the loss on drying specification limit is achieved.
