| abstract | 1472865 Thiohydrazoazetidinones SOC FARMACEUTICI ITALIA SpA 20 May 1975 [22 May 1974] 21419/75 Heading C2C Novel thiohydrazoazetidinones of the formula wherein R is hydrogen, (C 1 -C 4 )alkyl, cyanomethyl, thienylmethyl, furylmethyl, naphthylmethyl, benzyl, phenoxymethyl, phenylisopropyl, phenoxyisopropyl, 4 - pyridyl - thiomethyl or 1 - tetrazolyl - methyl; R<SP>2</SP> and R<SP>3</SP> represent (C 1 -C 4 )alkyl, a mononuclear aryl or heteroaryl radical, cyano, -COR<SP>4</SP>, -COOR<SP>4</SP>, -PO(OR<SP>4</SP>) 2 or -CONHR<SP>4</SP> is which R<SP>4</SP> is (C 1 -C 4 )alkyl or a mononuclear aryl or heteroaryl radical; or R<SP>2</SP> and R<SP>3</SP> together represent a residue having one of the formulae and Y is hydrogen or an aliphatic, aromatic, araliphatic or acyl residue, are prepared by opening the thiazoline ring of a compound having the formula by reacting a solution thereof with an azoderivative of the formula in the presence of an aqueous solution of an organic or inorganic acid at a temperature of from - 20 to + 80 C. The novel compounds are useful as intermediates in the preparation of cephalosporins as described and claimed in Specification 1,472,870. |
