Synthesis and stereochemical configuration of diastereomeric inherently chiral calixarenes with ABCH and ABCD type of substitution at the lower rim

By sulfonylation of tetra(p-tert-butyl)-27-propoxy-25-[N-(1-phenylethyl) carbamoylmethoxy]calix[4] arene diastereomeric inherently chiral calixarenes with the ABCH substitution at the lower rim were synthesized and separated by column chromatography. The

Diastereoselective reaction of 1,3-dihydroxy calixarene with acylisocyanates: New and easy approach for preparing inherently chiral calyx[4]arenes

The facile method of generating internal chirality into the calixarene with two hydroxy groups at the lower rim via an attached chiral substituent has been proposed. The reaction with acylisocyanates, catalyzed by a small amount of triethylamine, proceeds
