合成路线1
该中间体在本合成路线中的序号：(VII)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.
