Beckmann rearrangement of 3-aza-a-homo-4α-androsten-4,17-dione oxime and 3-oxo-13α-amino-13,17-seco-4-androsten-17-oic 13,17-lactam oxime

Rearrangements of 3-aza-A-homo-4α-androsten-4, 17-dione oxime produced a mixture of the normal lactam product and the product of a “second order” cleavage, an unsaturated nitrile. The lactam 3, 17α-di-aza-A, D-bishomoandrost-4α-ene-4, 17-dione was also obtained from the rearrangement of the syn-3-oxo-13α-amino-13, 17-seco-4-androsten-17-oic-13, 17-lactam oxime. The resolution of syn- and anti-isomers
3-氮杂-A-homo-4α-androsten-4、17-二酮肟的重排产生了正常内酰胺产物和“二级”裂解产物(不饱和腈)的混合物。内酰胺3,17α-di-氮杂-A,D-比绍莫雄罗斯-4α-ene-4,17-二酮也可以通过重新排列syn -3-oxo-13α-amino-13,17-seco-4获得-androsten-17-oic-13、17-内酰胺肟。的分辨率顺和反VIII的异构体通过柱色谱法来实现和它们的结构由光谱数据确定。
