  • 〖合成方法〗Halogenation of allylamine (I) with either bromine or sulfuryl chloride produced the corresponding (halomethyl)aziridines (II). Subsequent treatment of (II) with n-butyllithium at -78 C yielded 1-azabicyclobutane (III). Opening of the bicyclic system of (III) with formic acid followed by acid hydrolysis provided 3-hydroxyazetidine (IV). This was condensed with 2-(methylsulfanyl)thiazoline (V) to give thiazolinylazetidine (VI). Alternatively, 3-hydroxyazetidine (IV) was condensed with 2-chloroethyl isothiocyanate (VII) to give the intermediate thiourea (VIII), which cyclized to the thiazoline (VI). Conversion of the hydroxyl group of (VI) into the thioacetate (IX) was carried out by either coupling with thioacetic acid under Mitsunobu conditions or by conversion to mesylate (X) followed by displacement with potassium thioacetate. The required thiol (XI) was then obtained from (IX) by basic hydrolysis of the thioacetate ester.

Opening of the bicyclic system of (III) with formic acid followed by acid hydrolysis provided 3-hydroxyazetidine (IV). This was condensed with 2-(methylsulfanyl)thiazoline (V) to give thiazolinylazetidine (VI). Alternatively, 3-hydroxyazetidine (IV) was condensed with 2-chloroethyl isothiocyanate (VII) to give the intermediate thiourea (VIII), that cyclized to the thiazoline (VI). Conversion of the hydroxyl group of (VI) into the thioacetate (IX) was carried out by either coupling with thioacetic acid under Mitsunobu conditions or by conversion to mesylate (X) followed by displacement with potassium thioacetate. The required thiol (XI) was then obtained from (IX) by basic hydrolysis of the thioacetate ester. (Scheme 21984001a) 1-azabicyclobutane (III) was opened with thioacetic acid with concomitant N-acetylation yielding (XII). Further acid hydrolysis of (XII) gave 3-mercaptoazetidine (XIII). Condensation of (XIII) with either 2-(methylthio)thiazoline (V) or 2-chloroethyl isothiocyanate (VII) then produced thiazolinylazetidine (XI). (Scheme 21984001b) A further procedure consisted in the opening of 1-azabicyclobutane (III) with 2-mercaptothiazoline (XIV) to give (XV). Subsequent rearrangement of (XV) in the presence of methanesulfonic acid produced thiazolinyl azetidine (XI). (Scheme 21984001c) Condensation of (phosphoryloxy)carbapenem (XVI) with 3-mercapto-1-(1,3-thiazolin-2-yl)azetidine (XI) gave thioether (XVII). The p-nitrobenzyl ester group of (XVII) was then deprotected with Zn powder to afford the target carboxylic acid. (Scheme 21984001d) Synthesis of 268263: Halogenation of allylamine (I) with either bromine or sulfuryl chloride produced the corresponding (halomethyl)aziridines (II). Subsequent treatment of (II) with n-butyl lithium at -78 C yielded 1-azabicyclobutane (III). Opening of the bicyclic system of (III) with formic acid followed by acid hydrolysis provided 3-hydroxyazetidine (IV). This was condensed with 2-(methylsulfanyl)thiazoline (V) to give thiazolinylazetidine (VI).

(Scheme 26826301c) Condensation of (phosphoryloxy)carbapenem (XVI) with 3-mercapto-1-(1,3-thiazolin-2-yl)azetidine (XI) gave thioether (XVII). The p-nitrobenzyl ester group of (XVII) was then deprotected with Zn powder to afford carboxylic acid. Finally, treatment of (XVIII) with either iodo or chloromethyl pivalate (XIX) produced the target compound. (Scheme 26826301d)
