Irradiation of D-nor-5α-androstan-16-one oxime in methanol leads to a mixture of seco-nitriles; D-nor-13,16-seco-5α-androst-13(18)-ene-16-nitrile (3), D-nor-13,16-seco-5α-androst-12-ene-16-nitrile (7), 13ξ-methoxy-D-nor-13,16-seco-5α-androstane-16-nitrile (8), and 15-hydroxy-D)-nor-15,16-seco-5α-androstane-16-nitrile (9). These result from ionic α-fissions at either of the α-bonds. Low yields of three
D-nor-5α-androstan-16-one 肟在甲醇中的辐照会产生仲腈的混合物;D-nor-13,16-seco-5α-androst-13(18)-ene-16-nitrile (3), D-nor-13,16-seco-5α-androst-12-ene-16-nitrile ( 7), 13ξ-甲氧基-D-nor-13,16-seco-5α-androstane-16-nitrile (8), and 15-hydroxy-D)-nor-15,16-seco-5α-androstane-16-腈(9)。这些是由任一 α 键处的离子 α 裂变引起的。三种内酰胺收率低,17-aza-5α-androstan-16-one (6)、17-aza-5α,13α-androstan-16-one (11) 和 16-aza-5α-androstan-17-one (5),由photo-Beckmann
