โœฆ Synopsis


N-Cyan0 monoaza crown ethers were prepared by the reaction of cyanamide with oligoethylene glycol dichlorides or ditosylates in the NaH/DMSO reaction system and led. to the derivatives.

Crown ethers with functional groups such.as hydroxymethyl, 1) bromomethy12)

The sulfuric acid-promoted reaction of benzo-15-crown-5 O) and benzo-18-crown-6 (6) with aliphatic aldehydes, leading to the formation of anthracene crown et~rs, was studied. A substantial substiment effect on the reaction comse was found. For the isdmtyi group the highest yield was obtained, while
