CHLORINATION Bis(benzonitrile)dichloro-palladium(n). N-Chlorosucdnimide-Benzeneselenenyl chluride. N,N-Di-chlorouiethane. lodobenzene dichloride. Trifluoromethanesulfonyl chloride. [Pg.268]

Selective free-radical cMorinaiioa, Irradiation of the steroid (I) and an excess of lodobenzene dichloride in benzene with a 275-W sunlamp for 10 min., followed by treatment with silver perchlorate in aqueous acetone, gives an approximately I I... [Pg.264]

Remote functionalization of steroids (4,264-265 5,352-353). Breslow et al have modified their earlier procedure for chlorination of steroids at C9 or Ci4 by use of an external source of chlorine radicals, lodobenzene dichloride or sulfuryl chloride. Thus irradiation of the m-iodobenzoate of 3a-cholestanol (1) and lodobenzene dichloride in methylene chloride for 28 min. at 25° followed by saponification and acetylation leads to a mixture of 3a-cholestanyl acetate (18.4%) and the acetate of A -cholestene-3a-ol (2, 66%). Application of the... [Pg.298]

This functionalization has been used for a synthesis of cortisone from cor-texolone that is an attractive alternative to biological hydroxylation. Thus irradiation of (5) and lodobenzene dichloride gives, after dehydrohalogenation and saponification, the unsaturated alcohol (6). Hydroboration, oxidation, and deprotection of (6) affords dihydrocortisone, which had been converted previously into cortisone acetate and prednisolone acetate. [Pg.298]

CHLORINATION Antimony(V) chloride, lodobenzene dichloride. Molybdenum(V) chloride. Sodium hypochlorite. Sulfuryl chlorofluoride. Trichloroisocyanuric acid. [Pg.778]
