Pw. Zhou et al., DOUBLE ACTIVATION PREPARATION OF AN ACRIDINYL-ISOXAZOLYL-LEXITROPSIN, Bioorganic & medicinal chemistry letters, 7(19), 1997, pp. 2455-2456
The coupling of a sterically hindered acridinyl isoxazole ester direct
ly to the amine group of a lexitropsin is significantly improved by do
uble activation, using trimethylaluminum to activate the amine portion
and samarium (III) chloride to enhance the carboxylate reactivity. (C
