## Abstract Two improved procedures for the synthesis of 18‐hydroxycortexone and derivatives thereof are presented. One approach involved the development of an efficient method for preparing cyclic 20‐enol ethers as key intermediates for the oxygenation at position 21. In an alternative sequence, s

## Abstract A radical‐induced transfer of an entire functional group in steroid derivatives is described: the photolysis of an 11β‐nitrite function initiates the migration of a nitrile group from the 20‐ to the 18‐position. The reaction was used for the synthesis of new 18‐cyano‐corticoids.
