SYNTHESIS OF LARIAT ETHERS WITH PENDENT N,N-DIALKYL OXYACETAMIDE GROUPS

摘要

Synthetic routes to thirty crown ether compounds with pendent N,N-dialkylamide groups are reported. The new lariat ethers are based on sym-(R)dibenzo-13-crown-4-oxyacetamide, sym-(R)dibenzo-14-crown-4-oxyacetamide and sym-(R)dibenzo-16-crown-5-oxyacetamide, in which R = H or alkyl, and sym-(propyl)dicyclohexano-16-crown-5-oxacetamide. Two acyclic polyether analogues with pendent N,N-dialkylamide groups are also prepared. [References: 27]
