Abstract

A series of crown ether-like macrocyclic compounds 3 containing the 2, 6-dibenzyl-4- nitrophenol substructure have been prepared by cyclization reactions of disalicylideneacetone 4 with ditmylah 7 of oligoethylene glycols, followed by hydrogenation and double aldol condensation with nitromalondialdehyde. These compounds may be regarded as a section of a 1, 3-crowned calix [4] arene. X-ray dysb of two examples shows ...
