Octaethylene-glycol-dodecylether and dodecyl-β-D-maltoside are two widely used detergents in membrane protein studies. We describe here the synthesis of the 14C-labelled brominated analogues, and of the 14C-labelled forms. [1-14C]-5,6-Dibromo-dodecylether was prepared by coupling [1-14C]-(Z)-1-bromo-dodec-5-ene with octaethylene glycol followed by bromination. [1-14C]-5,6-Dibromo-dodecyl-β-D-maltoside was synthesised from [1-14C]-(Z)-dodec-5-en-l-ol via a coupling with α-bromohepta-O-acetyl-maltose followed by a deprotection step and bromination. Following similar methods, octaethylene-glycol-[1-14C]-dodecylether and [1-14C]-dodecyl-β-D-maltoside were also obtained. Copyright © 2001 John Wiley & Sons, Ltd.
