Abstract

Racemic protonated amino acid methyl esters were efficiently transported through a dichloromethane phase using L,L‐Cbz‐bis(15‐crown‐5)DOPA‐OMe as a carrier. The enantioselectivity was however marginal. The (15‐crown‐5) rings of the carrier were essential for affinity, as Cbz‐bis(12‐crown‐4)DOPA‐OMe was not a good host.
