The irradiation of 17 β‐hydroxy‐2‐oxa‐androst‐4‐en‐3‐one ( 1 ) yield a cyclopropane derivative 2 , which is the result of a rearrangement, formally analogous to the ‘type A rearrangement’ of the enones. Two other products, the dihydroxy compound 5 and the dimer 6 , have also been isolated ( Scheme 1 ).
