Unusual reaction of 16α,17α-epoxypregn-5-en-20-one derivative with hydroxylamine
摘要
The reaction of hydroxylamine and steroid obtained by the condensation of 16α,17α-epoxypregn-5-en-20-one with DMF dimethyl acetal proceeded through the involvement of the epoxide fragment and led to the formation of 3β-hydroxy-4′-hydroxylaminoandrost-5-eno[16,17-b]pyridine l′-N-oxide.
