Description

13 PROCESS FOB SAME 5 1 out of 23183 Pile 13036 T where X and Y represen the suhstituents where Ac designates an acyl radical or an organic carboxylic acid having 2 to 7 carbon or and Y together represent an oxygen atom and to a process for preparing these The compounds of the present invention are of value in steroid synthesis and especially in the synthesis of compounds described and claimed in the copending patent application from which the present application has been divided The novel compounds according to the present invention are obtained by the process which comprises the steps 5 7 9 reacting with an oxidizing if desired ethynylating the resulting by the action of an esterifying derivative of an organic carboxylic acid having from 2 to 7 carbon desired hydrating the ethynyl function of the ester of the formula wherein Ac represents the acyl of an organic carboxylic acid having from to 7 carbon by the action of water in the presence of a hydration According to the invention there are obtained the novel gonatr An ester CH out o 23183 File 13036 carboxylic wherein Ac represents the acyl of an organic carboxylic acid having to 7 carbon The process summarized by the flow diagram the of 13036 68 represents the of an organic carboxylic acid having from 2 to 7 carbon Shis process is essentially characterized in that 5 7 is subjected to the action of an oxidizing agent under the usual conditons to oxidize the hydroxy group to a An ethynylating agent is reacted with the resultant 7 9 thus obtainin This latter compound esterifled the aid of a functiona derivative of an organic carboxylic acid havin from 2 to 7 carbon atoms to give a 5 79 Δ The ethynyl function of this ester is catalytically hydrated to give a 5 7 The performance of the process of invention may be characterized advantageously by the following The oxidizing agent utilized to oxidize the 5 79 group of into the 17 is preferably chromic acid and the reaction is conducted in the presence of sulfuric acid in an acetonic media The ethynylating which is allowed upo the can be any ethynylating agent conventionally used to ethynylate a 17 ketone however it preferable out of 13036 g Is esterifled by means of a functional such as an acid chloride an of an organic carboxylic acid having from 2 to 7 carbon When the reaction conducted with acetic acid it is preferable to conduct the same in the presence of a strongly acidic such as oluene sulfonic She ethynyl function of the 5 79 acyloxy is hydrated according to conventional methods in steroid Preferably the reaction is conducted in a dilute in the presence of a hydration such as a mercury salt of or an ion exchange resi containing mercuric The following example illustrates the It is to be that it presents no limiting EXAMPLE 5 Step A solution of 24 gm of 5 Δ in 480 cc pure acetone was cooled and within a space of 5 minutes the following solution was Chromic acid gm Water cc out of 23183 Pile 13036 mixture was further agitated for another 15 then poured into of The a mixture was extracted with methylene The extracts were with an aqueous saturated solution sodium and thereafte with water until the wash waters were neutral and finally The extrac wa then evaporated under to and the solid residue obtained was crystallized from isopropyl After vacuum filtering and drying gm of 5 79 were This product occurred in the form of colorless having melting point of and a specif rotation in The product was insoluble in and soluble in benzene and methylene This compound is not described in the literature 5 7 9 Step A solution of lithium acetylide in a tetrahydrofuran media was by allowing acetylene to bubble through a mixture of cc of and 1560 cc of solution in over a period of 3 hours at This solution was heated to over a period of 5 gm 5 79 dissolved in 175 cc of were The was heated to reflux for 2 then cooled to and within a period of 30 without exceeding 3000 cc of an aqueous saturated solu ion of ammonium chloride were introduced The solution was The aqueous phase was separated and extracted with The combined organic phases with dried over sodium sulfate and evaporated to A resin thus which was dissolved in methylene chloride and subjected to On elution chloride containing of gm of η Q were product was utilized as such the following This compound is not in the Step III Ac To a solution of of 5 7 in cc of acetic acid of sulfonic acid monohydrate were added at a temperature of For a period of 20 hours this mixture was agitated at a temperature of 600 cc of water were introduced in the reaction mixture and it was agitated 2 hours at The aqueous mixture was extracted with methylene The combined organic phases were washed successively with then with a saturated solution of sodium bicarbonate and finally with water until j the wash waters were dried over sodium sulfate and evaporated vacuum to In this manner a resin was which was dissolved in methylene and subjected to chromatography through silica On elution with methylene chloride containing of of 17 with Ac were The product obtained was as such for the following This compound is not described in he 1 ou of Pile 13036 5 7 with Ac were The product was utilized as such for the following compound is not described in the insufficientOCRQuality
