The synthesis of a new class of corticosteroids with rings A and B rearranged to a 10 (5→4)‐ abeo system is reported. New methods are presented for the preparation and hydrolysis of corticosteroid derivatives, side‐chain‐protected by bis‐methylenedioxy groups, used as intermediates in some of the examples given.
