The Syntheses of Some Androstano [2, 3-g] pteridines
Reaction of 17β-hydroxy-5α-androstan-3-one morpholine or pyrrolidine enamine with 6-amino-5-nitrosopyrimidines or 6-amino-5-phenylazopyrimidines led to the formation of the corresponding androstano [2, 3-g] pteridines. These steroidal pteridines were also prepared by the Isay's pteridine synthe...

| Zusammenfassung: | Reaction of 17β-hydroxy-5α-androstan-3-one morpholine or pyrrolidine enamine with 6-amino-5-nitrosopyrimidines or 6-amino-5-phenylazopyrimidines led to the formation of the corresponding androstano [2, 3-g] pteridines. These steroidal pteridines were also prepared by the Isay's pteridine synthesis from 17β-hydroxy-5α-androstan-2, 3-dione and the corresponding 5, 6-diaminopyrimidines. |
