| titleOfInvention | 3- (Fluorosulfonyl) oxy substituted with cef, oxacef and carbacef and a process for their preparation |
| abstract | 3-(fluorosulphonyl)oxy substd. cephems, oxa cephems and carbacephems of formula (I) are new: where Z = S, O, sulphoxide, sulphone or CH2; Q = H, amide protecting grp. or acyl grp. of a 7-acylaminocephalosporin antibiotic; P = H, carboxy protecting grp. or physiologically hydrolyzable ester. A process of prepn. of 3-substd. cephems is also new, In the formula R1 = H, 2-6C alkenyl, 2-6C alkynyl, 2-6C alkadienyl, 6-10C aryl (opt. substd. with 1-3 of A) or heterocycle (opt. substd. with 1-3 of A); A = 1-3C alkyl, OH, 1-3C alkoxy, halo, NH2, 1-3C alkylamino, di(1-3C)alkylamino, NO2, carboxyl, 1-3C alkoxycarbonyl or CN; L = fluorosulphonyloxy, 4-nitrobenzesulphonyloxy or 4-bromophenylsulphonyloxy; R2 = organic grp. typical of organostannane coupling processes; M = Pd (II) or Pd(O) catalyst. |
