The hydrolysis of a series of norbornane-type carboxylic esters catalyzed by pig liver esterase (PLE) has been investigated. It was found that an exo-eer function (syn to the C7 methylene group) is hydrolyzed with high preference. Enantioselective hy

Cyclopropanation of tricyclo[5.2.1.02,6]deca-2(6),8-dien-3-one using dimethylsulfoxonium ylide gave a highly strained annulated cyclopropane in 68% yield with complete exo-face selectivity. Nucleophilic epoxidation gave a strained epoxide in 68% yiel

Tricyclo[5.2.1.02,6]deca-2(6),8-dien-3-one contains a highly strained central double bond due to geometrical constraints imposed by the tricyclic skeleton which does not allow optimal sp2 hybridization at the C2 and C6 bridgehead positions. Michael a

Alkylation at C 6 of tricyclo[5.2.1.0 2,6 ]deca-4,8-dien-3-one (R=H) was achieved by treatment of 6-bromotricyclo[5.2.1.0 2,6 ]deca-4,8-dien-3-one with lithium dimethylcuprate and subsequently with an appropriate electrophile. The best results were o

We describe the allylation and propargylation of 3-formylcephalosporins under zinc-mediated, aqueous Barbier conditions, from which the corresponding homoallylic alcohols are produced in good yields and with good-to-excellent diastereoselectivity. (

The cephalosporin antibiotic cephradine can form clathrate-type complexes with appropriate guest molecules. When a mixture of o- and p-disubstituted benzene derivatives is subjected to complexation with cephradine, a high preference and in some cases

The stereoselectivity of the nucleophilic addition of lithium dimethylcuprate and lithium di-n-pentylcuprate to 6-substituted tricyclo[5.2.1.02,6]deca-4,8-dienones was investigated. It was shown that substituents at the 6-position can either exert a
