N2 - Inherently chiral anti-O,O′-dibenzyl- and anti-O,O′-dibutyl-p-tert-butylthiacalix[4]arenes 4 and 6 are resolved as (S)-2-methoxy-2-(naphthalen-1-yl)propionic esters by flash chromatography. The absolute stereochemistries were determined to be (Sa)-(+)-4 and (Sa)-(+)-6 by X-ray crystallographic analyses.
