ABSTRACT:
A multi-step, stereospecific total synthesis of steroids is disclosed. The starting materials for this process are the relatively inexpensive and readily available m-alkoxy acetophenones. The process is suitable for the preparation of racemic or optically active, medicinally valuable steroids, particularly A-ring aromatic steroids. This process features an early optical resolution and a unique asymmetric induction which insures the correct stereochemistry of the final steroidal product.
