WebDec 5, 2003 · The separation by crystallization of the pair of cryptophane diastereomers 1 a and 1 b, obtained in 1:1 ratio by treating racemic anti cryptophanol-A (2) with (−)-camphanic acid chloride, provided a substantial amount of optically pure material (diastereomeric excess>98 %).Subsequent hydrolysis afforded the optically pure cryptophanol-A … WebThe first xenon biosensor, developed by Pines and co-workers in 2001, covalently modified cryptophane-A with a peptide as the solubilizing element and biotin as the targeting element. (24) A measurable shift, ∼2.3 ppm, was observed for the xenon biosensor bound to avidin.
