of tetramethoxyresorcarene diastereomers is reported. The reactions of inherently chiral C4-symmetric tetramethoxyresorcarene derivatives with the chiralauxiliary (–)-(S)-1-phenylethylisocyanate gave new diastereomeric carbamate compounds in good yields. The diastereomers were separated by simple silica chromatography and then converted by hydrolysis into their parent tetramethoxyresorcarenes to

A new reactive postion at the upper rim of inherentlychiralresorcin[4]arenes was introduced through cleavage of an up to now unreactive methoxy group through the demethylating reagent 9-I-9-BBN. Conservation of the inherent chirality was warranted through the use of a protecting group at the free phenol group.
