2-cyclopenten-1-ones bearing an acylamino side-chain at C-4 and an acetic acid residue at C-2 were designed as potential alkylating inhibitors of penicillin sensitive enzymes. Compounds 11 and 12 efficiently prepared from the readily available 2-phenylsulfonyl-4-methoxycarbonyl-cyclopentan-1-one 3. They were inactive in all tests.
