Abstract

1502513 Steroid[16α,17-b] dioxanes E R SQUIBB & SONS Inc 13 May 1975 [8 Nov 1974] 20206/75 Heading C2U The invention comprises #<SP>4</SP> steroids of Formula I and their #<SP>1,4</SP>, #<SP>4,6</SP> and #<SP>1,4,6</SP> analogues wherein A 1 is selected from (the valency on the left being attached to the 17- oxygen atom); P and Q are each H, Me or halo; X is Cl or F; Z is H, halo, OH or OCOR<SP>5</SP>; R<SP>1</SP> is H, C 1-8 alkyl, Ph, or Ph substituted with C 1-8 alkyl, C 1-8 alkoxy or halo; R<SP>2</SP> is H or C 1-8 alkyl; and R<SP>3</SP> and R<SP>5</SP> are each C 1-8 alkyl, C 3-6 cycloalkyl, Ph, or Ph substituted with C 1-8 alkyl, C 1-8 alkoxy or halo. The inventive compounds are prepared from compounds of formula by synthesizing the 16α,17α-dioxane ring as shown in the reaction scheme infra and, at any of the stages marked *, producing a 9,11-dihalo grouping by dehydrating to #<SP>9(11)</SP>-compounds (e.g. with POCL 3 /py or MsCl/py) followed by reaction with N-chlorosuccinimide and HX. Also at any appropriate stage #<SP>6</SP> unsaturation may be introduced (e.g. with DDQ), a 21-ester group hydrolysed, or a 21-hydroxy group replaced by H or halo via the 21-methanesulphonate. (R<SP>1</SP> and R<SP>3</SP> are as above; R is alkyl; R<SP>4</SP> is as R<SP>1</SP> except H). Reagents.- (a) THP . O-CH 2 CHN 2 ; (b) AcOH/H 2 O; (c) MsCl/py; (d) NaHCO 3 /DMS; (e) (RO) 2 CH-CHN 2 ; (f) TsOH/PhH; (g) HCl/THF; (h) CH 2 =C(R<SP>1</SP>)-CHN 2 ; (i) mchloroperbenzoic acid; (j) H 5 IO 6 ; (k) NaBH 4 ; (l) (R<SP>3</SP>CO) 2 O or R<SP>3</SP>COCl; (m) K 2 CO 3 /MeOH; (n) Fetizon's reagent; (p) H 5 IO 6 ; (q) and (r) TsOH/PhH. 16,17-Cycloborates are prepared from 6α- fluoro-11#,16α,17,21 - tetrahydroxypregna - 1,4- diene-3,20-dione, 21-chloro-11#,16α,17-trihydroxypregna - 1,4 - diene - 3,20 - dione and 11#,16α,17,21 - tetrahydroxy - 6α - methylpregna-1,4-diene-3,20-dione by reaction with boric anhydride in methanol (Examples 5, 8, 18). 2 - (Tetrahydropyran - 2 - yloxy) - 1 - diazoethane (Example 1) and 2-phenyl-3-diazo-1- propane (Example 7) and their precursors are prepared as described in Specification 1,498,132. Anti-inflammatory compositions for oral and topical administration comprise a compound of the invention and a carrier.
