Compound can be prepared in two different ways: 1) By dehydration of 13beta-ethyl-11beta,17beta-dihydroxy-17alpha-ethynyl-gona-4,9-diene-3-one (IV) with 60% formic acid at 100 C or with perchloric acid in methylene chloride containing acetonitrile. 2) The ketalization of 13beta-ethyl-gona-4,9,11-triene-3,17-dione (I) by means of glycol (A) and oxalic acid in dichloroethane affords 3-ethylenedioxy-13beta-ethyl-gona-4,9,11-trien-17-one (II), which is then treated with methylmagnesium bromide (B) and acetylene (C) in THF to yield 3-ethylenedioxy-13beta-ethyl-17beta-hydroxy-17alpha-ethynyl-gona-4,9,11-triene (III). Finally, this compound is hydrolyzed in an acidic medium.

RU-16117 is synthesized from D9(11)-estradiol (I). After protecting the hydroxyl groups by the formation of a benzyl ether (II), the double bond is hydrated by hydroboration, followed by oxidation with hydrogen peroxide in alkali. The alcohol thus formed (III) is treated with sodium hydride and then methyliodide (IV). After deprotection of the 3 and 17 hydroxyl groups (V), the C-17 hydroxyl is oxidized to a ketone by chromic oxidation (VI) and the 17-alpha-ethynyl group is introduced directly with potassium acetylide.

Reaction of 9a-hydroxyandrost-4-ene-3,17-dione (I) with benzenesulfinyl chloride and pyridine gives the corresponding sulfinate (II), which by treatment with TsOH in refluxing chloroform yields androsta-4,9(11)-diene-3,17-dione (III). Reaction of the androstadienedione (III) with acetylene by means of potassium tert-butoxide in THF affords the 17a-ethynyl derivative (IV), which is treated with phenylsulfenyl chloride and TEA at ­70 C to provide the sulfenate ester (V). Rearrange-ment of sulfenate (V) by warming at ­40 C gives the allene sulfoxide (VI), which is treated with sodium methoxide in methanol at 25 C to yield the enol ether sulfoxide (VII). Then, by refluxing in methanol, an equilibrium between sulfoxide (VII) and sulfenate (VIII) occurs. Reaction of the non-isolated sulfenate (VIII) with the thiophile trimethyl phosphite affords the 17a-hydroxy enol ether (IX), which is finally converted to anecortave acetate by either treatment with peracetic acid and NaHCO3 in dichloromethane or bromination with Br2 and pyridine in dichloromethane to give compound (X) followed by treatment with KOAc, KI and AcOH in refluxing acetone.

2) Intermediate (IX) can also be obtained as follows: The cyclization of 4-cyanobenzoic acid methyl ester (XII) with acetylene at 15 Atm by means of cobaltocene in toluene at 180 C gives 4-(2-pyridyl)benzoic acid methyl ester (XIII), which is saponified with NaOH in methanol to the corresponding acid (XIV). The activation of (XIV) with isobutyl chloroformate yields the mixed anhydride (XV), which is condensed with N-(tert-butoxycarbonyl)-L-phenylalaninal (XVI) and KCN in dichloromethane, affording (XVII). The reaction of (XVII) with tert-butyl carbazate (V) by means of acetic acid in methanol gives hydrazone (XVIII), which is reduced to hydrazine (XIX) by means of sodium cyanoborohydride in THF. The isomerization of (XIX) by means of 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTDE) in hot diglyme yields hydrazide (XX), which is finally reduced to intermediate (IX) with diisobutylaluminum hydride in dichloromethane/THF.

4-Bromo-3-fluorotoluene (I) is converted into the Grignard reagent (II) with magnesium in boiling Et2O, and subsequently added to cyclopropylacetonitrile (III) to produce ketone (IV). Condensation of (IV) with hydroxylamine affords oxime (V), which is further alkylated with benzyl bromide to yield the O-benzyl oxime (VI). Asymmetric reduction of oxime (VI) with borane in the presence of the aminoalcohol chiral auxiliary (VII) provides the (S)-amine (VIII). Reaction of amine (VIII) with ammonium thiocyanate and benzoyl chloride, followed by treatment with hydrazine hydrate, gives rise to the thiourea (IX). Friedel-Crafts acylation of 4-chloro-2-methoxytoluene (X) with 2-bromopropionyl bromide (XI) employing AlCl3 furnishes the bromo ketone (XII). Then, condensation of thiourea (IX) with bromo ketone (XII) in the presence of Et3N in boiling EtOH gives rise to the aminothiazole (XIII). Finally, alkylation of the amino group of (XIII) with propargyl bromide (XIV) and NaH furnishes the title compound

合成路线9

该中间体在本合成路线中的序号:(III)

The known oxazolidine methansulfonate (I) is reacted with NaN3 in hot DMF to produce azide (II). Then, condensation of azide (II) with acetylene (III) at 90 C in a pressure vessel gives rise to the target triazole derivative.
