Abstract
To test the eventual involvement of sterols with a cyclopropane containing side chain in bioβmethylation processes, 24,25βmethanocholestβ5βenβ3Ξ²βol (5) and 24,25βmethanoβ26βmethylcholestβ5βenβ3Ξ²βol (6) were synthesized. Together with the naturally occurring cyclopropane petrosterol (1), they were submitted to acid isomerization to provide chemical models for some of their potential metabolites.

A novel thermotropic side-chain liquid crystalline ionomer (LCI) containing sulfonic acid groups on the side-chain was synthesized by graft copolymerization of mesogenic monomer 4-allyloxy-benzoxy-4 -methoxyphenyl (ABM) and nonemesogenic monomer 4-allyloxy-azobenzene sulfonic acid (AABS) upon polyme
