Photolysis of 6-methylcholest-5-en-3β-ol nitrite and 4,4,6-trimethylcholest-5-en-3β-ol nitrite in benzene with monochromatic light respectively gave a seven-membered cyclic hydroxamic acid arising from rearrangement albeit in low yields. Photolysis of 3α-methylcholest-5-en-3β-ol nitrite and 3α,4,4-trimethylcholest-5-en-3β-ol nitrite respectively gave a nitroso dimer arising from β-scission.
6-methylcholest-5-en-3β-ol 亚硝酸盐和 4,4,6-trimethylcholest-5-en-3β-ol 亚硝酸盐在苯中用单色光分别光解得到重排产生的七元环异羟肟酸,尽管在产量低。3α-methylcholest-5-en-3β-ol 亚硝酸盐和 3α,4,4-trimethylcholest-5-en-3β-ol 亚硝酸盐的光解分别产生由 β 断裂产生的亚硝基二聚体。
