Lariat ethers of various ring size and substitution are synthesized and characterized by physical data and chemical analysis.The extraction behaviour of the crown compounds towards Na+, K+, Cs+ and Ag+ in a picric acid solution has been investigated.The extraction constants for 1:1 and 1:2 complexes are determined using the equilibrium distribution data.The results show that the flexible side chain in the investigated compounds has in no case a positive effect on the metal picrate extraction.
Synthesis and β-Adrenergic Blocking Activity of New Aliphatic Oxime Ethers

New β-adrenergic blocking agents, most of which do not contain an aromatic nucleus, were synthesized.They were derived either from alkylamino-aliphatic oxime ethers, or alkylamino-aliphatic ethers.Most active among these are O-acetoxime (8; trachea pA2=7.65) and 1-isobutoxy-3-(tert-butylamino)-2-propanol (15, trachea pA2=7.49), both of which displayed bronchoselectivity (β2/β1 ratio ca. 15).The role and importance of the aromatic nucleus in this class of compounds are discussed
