Abstract
1525063 D-homo steroids F HOFFMAN-LA ROCHE & CO AG 9 April 1976 [9 April 1975] 14623/76 Heading C2U The invention comprises #<SP>4</SP> and #<SP>4,6</SP> 19-nor- D-homosteroids of formula (wherein R<SP>17a</SP> is hydroxy, acyloxy, C 1-7 alkyl or C 1-7 alkoxy; and R<SP>21</SP> is H, F or Cl); and their preparation (a) from the corresponding 3#- hydroxy-#<SP>4</SP>, #<SP>5</SP> or #<SP>5(10)</SP> compounds by oxidation (to give 3-oxo-#<SP>4</SP> or #<SP>4,6</SP>); (b) from the corresponding compounds in which the 3-oxo group is functionally converted (e.g. enamines, enol ethers and thioethers, ketals, thioketals) by hydrolysis; (c) from the corresponding #<SP>17a(20)</SP>- enes by oxidation to give a 17a-hydroxy-20-oxo grouping (conventional one- and two-stage procedures are described); (d) from the corresponding 21-ols by 21-halogenation (direct or via 21-sulphonates); (e) from the corresponding 10-formyl compounds by deformylation, e.g. with alcoholic NaOH or KOH; (f) from the corresponding saturated 5-hydroxy or 5-halo compounds by 4,5-dehydration or dehydrohalogenation, e.g. with an acid or base; (g) from the corresponding #<SP>17(17a)</SP>-enes by reductive alkylation (to give R<SP>17a</SP>=alkyl), e.g. with alkyl iodide/Li/NH 3 /THF, and with intermediate protection of the 3-oxo group; (h) from the corresponding 17aα-H compounds by 17aα-hydroxylation, e.g. with O 2 /HOBu<SP>t</SP>/Bu<SP>t</SP>OH/P(OMe) 3 / DMF, and with intermediate protection of the 3-oxo group. Compounds I are interconvertible by (i) 6,7-dehydrogenation, and (ii) acylation or alkylation of 17aα-OH. 3# - Hydroxy - D - homopregna - 5,17 - dien - 20 - one # 3# - acetoxy - 17α,17a - epoxy - D - homopregn - 5 - en - 20 - one # 3# - acetoxy - 17# - bromo - 17a - hydroxy - D - homopregn - 5 - en - 20 - one # 3# - acetoxy - 17a - hydroxy - D -homopregn - 5 - en - 20 - one # 3# - acetoxy - 17a - alkanoyloxy - D - homopregn - 5 - en - 20 - one (where "alkanoyloxy" is. acetoxy or hexanoyloxy) # 5 - bromo - 3# - acetoxy - 17a - alkanoyloxy - 6# - hydroxy - D - homo - 5α - pregnan - 20 - one # 5 - bromo - 3# - acetoxy - 17a - alkanoyloxy - 6#,19 - epoxy - D - homo - 5α - pregnan - 20 - one # 3# - acetoxy - 17a - alkanoyloxy - 19 - hydroxy- D - homopregn - 5 - en - 20 - one # 3# - acetoxy - 17a - alkanoyloxy - 19 - (2 - tetrahydropyranyloxy)- D - homopregn - 5 - en - 20 - one # 3# - hydroxy - 17a - alkanoyloxy - 19 - (2 - tetrahydropyranyloxy) - D - homopregn - 5 - en - 20 - one # 17a - alkanoyloxy - 19 - (2 - tetrahydropyranyloxy) - D - homopregn - 4 - ene - 3,20 - dione # 17a - alkanoyloxy - 19 - hydroxy - D - homopregn - 4 - ene- 3,20 dione # 17a - alkanoyloxy - 3,20 - dioxo - D - homopregn - 4 - en - 19 - al.
