Synthesis and antimicrobial activity of brominated resorcinol dimers
摘要:
Dibrominated resorcinol dimers were synthesized by reaction of 4-bromoresorcinol with aldehydes under reflux in ethanol in the presence of HCl. Subsequent dehalogenation yielded the corresponding monobrominated compounds and a fully dehalogenated dimer. Of the dimers, 6,6'-((4-hydroxyphenyl)methylene)bis(4-bromobenzene-1,3-diol) (4) displayed potent antibacterial activity and inhibitory activity against isocitrate lyase Candida albicans.

Calix[4]arenes containing one or two resorcinol units incorporated via their 2,6-positions were prepared by fragment condensation. Due to the cyclic array of intramolecular hydrogen bonds these molecules assume the cone-conformation.
