title: Steroidal seven-membered A-ring epoxy lactones by oxidation of the corresponding Delta 4-3-ketosteroids.
abstract: Treatment of Delta 4-3-ketosteroids with m-chloroperbenzoic acid at 0 degrees C produced the corresponding steroidal seven-membered A-ring epoxy lactones. The adopted procedure allowed for efficient recovery and separation of the products with definite stereochemistry.
