Description
458 684 O H Ri Sflßoec III fiNw/ï coon vari Rl, R och PG definieras som ovan, med fosfortribromid, och ozonolysering av den resulterande föreningen med formel IV R s i om Iv O N / COOR vari Rl, R och PG definieras som ovan, i ett lösningsmedel vid en temperatur av från -80°C till -50°C. 6-substituenten kan antingen uppvisa alfa- eller beta-oriente- ring, varvid alfa-orientering är föredragen. När Rl är lägre hydroxíalkyl kan kolatomen som bär hydroxifunktionen såväl vara R som även S men är emellertid företrädesvis R.
Kolatomen i ställning 5 uppvisar endast R-konfigurationen.
Föreningarna med formeln (IVa) framställes sålunda enligt föreliggande uppfinning enligt följande reaktionsschema i vilket PG är en dimetyl-tert.butylsílyl-, difenyl-tert.butyl- silyl- eller trimetylsilyl-grupp. 458 684 458 684 Förfarandet enligt uppfinningen omfattar skyddandet av den fria hydroxigruppen hos förening (II) (framställd såsom besk- rives i GB-PS 2 043 639) med en skyddsgrupp, reduktion av sulfoxidfunktionen hos den erhållna föreningen (III), ozonolys av båda kol-kol-dubbelbindníngarna i den erhållna föreningen (IV).
Reduktionen kan genomföras under användning av fosfortribromíd vid en temperatur av -40 till -20°C i ett lösningsmedel, såsom vattenfri dimetylformamid. Ozonolysen kan åstadkommas vid en temperatur av -80 till -50°C i ett lösningsmedel, såsom dietyleter, metanol eller - företrädesvis - diklormetan.
Tvà kännetecken hos föreliggande uppfinning fordrar en ytter- ligare kommentar. Kolatomen i ställning 5 vars R-konfiguration "den enda väsentliga stereokemiska fordran för antibiotisk verkan" (H.R. Pfaendler, J. Gosteli och R.B. Woodward, J.Am.Chem.Soc. l0l, 1979, är 6306) behåller sin konfiguration fràn föreningen (II) ända fram till den önskade slutförening- en. Kol-svavelbindningen förstöres icke i något steg.
Föreningar med den allmänna formeln IVa som erhålles enligt föreliggande uppfinning är lämpliga mellanprodukter vid fram- ställning av penemer som besitter anti-bakteriell aktivitet som beskrives i GB-PS 2 043 639.
Uppfinníngen àskàdliggöres närmare medelst följande exempel varvid följande förkortningar användes, PNB för p-nitrobensyl, TBDPS för tert.-butyldifenylsilyl och TBDMS för tert.-butyldi- metylsilyl.
