A method for producing an organolithium compound includes the step of reacting an aromatic compound or a halogenated unsaturated aliphatic compound and a lithiating agent in the presence of a coordinating compound containing three or more elements having a coordinating ability in a molecule, at least one thereof being a nitrogen element, or a coordinating compound containing three or more oxygen elements having a coordinating ability in a molecule, at least one of the groups containing the oxygen elements having a coordinating ability being a tertiary alkoxy group, at a temperature of −40° C. to 40° C.

A new type of homopolymers, PMAOE, bearing acid‐cleavable cationic side‐chains is synthesized and characterized. PMAOE is obtained via free radical polymerization, and they could efficiently bind and condense plasmid DNA at neutral pH. The strength of DNA binding is dependent on the length of PMAOE chains. NMR analysis reveals that hydrolysis of the ortho ester group of PMAOE follows an exocyclic mechanism

Polysubstituted cyclopentadiene compound, in which at least one substituent is of the form -RDR'.sub.n, in which R is a bonding group, D is a hetero atom selected from group 15 or 16 of the Periodic System of the Elements, R' is a substituent and n is the number of R' groups bonded to D, and in that at least one further substituent is a branched alkyl group.
A class of 7-oxo-2,6-diazabicyclo-[3.2.0]-heptane-6-sulfonic acid compounds substituted at the two position of the bicyclic ring with a heterocyclylaminocarbonyl group or a carbocyclylaminocarbonyl group are β-lactamase inhibitors. The compounds and their prodrugs and pharmaceutically acceptable salts are useful in the treatment of bacterial infections in combination with β-lactam antibiotics. In particular, the compounds are suitable for use with β-lactam antibiotics (e.g., imipenem and ceftazidime) against micro-organisms resistant to β-lactam antibiotics due to the presence of the β-lactamases.
