Various symmetric and non-symmetric polynorbornadienes having a variety of ester groups and carboxyl groups were synthesized by ring-opening metathesis polymerization (ROMP) …
Symmetric organic compounds are generally obtained inexpensively, and therefore they can be attractive building blocks for the total synthesis of various pharmaceuticals and natural …
A small series of norbornane bisether diguanidines have been synthesized and evaluated as antibacterial agents. The key transformation—bisalkylation of norbornane diol 6—was not …
A highly convergent total synthesis of (−)-laurenditerpenol has been accomplished through an organolithium to aldehyde nucleophilic addition. Preparation of the prerequisite key …
Selective monooxidation of symmetric dialdehydes in aqueous media have been investigated for several symmetric dialdehydes. The best conditions apply 1.1 equivalents of …
Separation of optical isomers obtainable from trans‐norborn‐5‐ene‐2, 3‐dicarboxylic acid methyl and tert‐butyl monoesters was performed by crystallization of the respective salts …

Libraries of polynorbornadienes were synthesized with good yields with a ruthenium- containing 2nd generation Grubbs catalyst by ring-opening metathesis polymerization …
The conditions of the practical selective monohydrolysis of symmetric diesters we previously reported have been modified and applied to selective monohydrolysis of bulky symmetric …
