Synthetic routes to forty-seven dibenzo-16-crown-5 compounds with pendant carboxylic acid groups are reported. When taken together with previously described lariatether carboxylic acids, these new compounds provide several series with systematic structural variations including changes in the identity and attachment site(s) of one or more lipophilic groups and the length of the spacer that connects

Synthetic routes to forty-four dibenzocrown ether alcohols are reported. The new crown ether com pounds are based on a sym-dibenzo-16-crown-5 platform. Most have a hydroxy group and an alkyl, aryl, aralkyl, alkenyl, alkynyl, or perfluoroalkyl group on the central carbon of the three-carbon bridge. Others have substituted benzene rings and either a hydroxy or -O(CH2)nOH group attached to the central

related dibenzo-16-crown-5 lariat ethers with pendant ester and ethergroups are prepared. Structural variations within the series of alkyl lariat etheresters include changes in the O-alkyl group, attachment site and nature of the lipophilic group, and length of the spacer, which connects the estergroup to the polyether framework. Also synthesized are bis(crown ether) diesters with two dibenzo-16-crown-5
