N2  - .The two heterocyclic compounds produced on irradiation of 3&#946;-acetoxy-6- nitrocholest-5-ene (1) have been shown by chemical degradation to be 3&#946;-acetoxycholest-4-eno[6,5,4-cd]isoxazole (3) and 3&#946;-acetoxy-A- norcholestano[6,5-c]-2'-isoxazoin-5'-one (4), while those formed from 6-nitrocholest-5-ene (2) are the analogous compounds, cholest-4-eno[6,5,4-cd]isoxazole (5) and A-norcholestano[6,5-c]-2'-isoxazolin-5'- one (6).
