dataset
posted on 2007-06-07, 00:00 authored by Katerina Kogan, Silvio E. BialiKetocalix[6]arene 2e was prepared by CrO3 oxidation of the methylene groups of 2a, followed by hydrolysis of the acetate groups. 2e undergoes
intramolecular SNAr reactions under the usual methylation conditions (MeI, base), yielding mono- and dixanthone calixarene derivatives.
