General description

3,6-Dithia-1,8-octanediol is a secondary sulfur-based catalyst poison.

Application

3,6-Dithia-1,8-octanediol has been used:
  • as exogeneous chelator to evaluate a membrane-permeable copper-selective fluorescent sensor for imaging of kinetically labile copper pools
  • in asymmetric total synthesis of (+)-6-epi-castanospermine and polyhydroxylated alkaloid

Functionalized erythromycin 9-oxime derivatives are 6-O-allylated under mild conditions using substituted allyl tert-butyl carbonates under palladium(0) catalysis. This allylation works well where traditional ether-forming protocols function poorly. Allyl tert-butyl carbonates provide higher yields in this reaction than lesser substituted carbonates
