Zusammenfassung:ThienoÄ2,3-dÜÄ1,2,3Üthiadiazoles of formula (I) and their salts are new. X = H, halo, 1-4C alkyl, SR8, NR9R10, CH2OH, CHO or COOR8; R8-R10 = H, 1-4C alkyl, benzyl, 1-4C acyl or benzoyl; Z = H, halo or methyl (optionally substituted by 1-3 optionally substituted heteroatoms (O, S and/or N)); provided that Z is not methyl when X is COOEt. Also claimed are tetrahydrofuran hydrazone intermediates of formula (II) and an organolithium compound of formula (III) as a solution in an aprotic solvent. T = COY, CONY2, SO2Y or COOU; U = 1-8C alkyl or aryl (both optionally substituted); and Y = H or as for U.
