Abstract
Halocarbonyl-penicillins - useful as intermediates for new semisynthetic antibiotics. Title cpds. of formula (I): where R is an opt. substd. aromatic, heterocyclic, aliphatic or alicyclic gp.; X is halogen; R2 is a radical contg. the 6-aminopenicillanic gp.; are prepd. by reacting a cpd. of formula (I)f R2 = X , with (II), where R1 is H or a radical contg. a prim. amino, or a salt or ester of this cpd., under anhydrous conditions in the presence of a weak base. Pref. R1 is R3-(CH)nCO (where R3 is as R, and n is a whole no.).
