Amino compounds and angiotensin IV receptor agonists

A process for preparing an anion exchange membrane, which comprises subjecting a carboxylate membrane made of a copolymer having repeating units of the formula: ##STR1## wherein X is F or CF.sub.3, l is an integer of from 0 to 5, m is 0 or 1, n is an integer of from 1 to 5, and p/q is from 4 to 16, and R is an alkyl group, to an acid or base treatment, and then introducing anion exchange groups thereinto.

Process for preparing a highly selective fluorinated anion exchange

A process is described whereby esters of 3-(2,2,2-trichloroethyl)-2,2-dimethylcyclopropane-1-carboxylic acid are prepared predominantly in their cis isomer form. The process comprises treating a 4,6,6,6-tetrachloro-3,3-dimethylhexanoate with an alkali metal tert-alkoxide under controlled conditions of temperature in the presence of a defined solvent-cosolvent mixture. The products of the process are intermediates in the production of pyrethroid insecticides.

Process for preparing high cis

A process for producing 3-cyanomethyl cyclopentanone derivatives which are useful precursors of fragrant components in jasmine and analogous thereof such as methyl jasmonoate, methyl dihydrojasmonate, etc., is disclosed. In the process, the jasmonoates are produced starting from .beta.-dicarbonyl compounds and azides through several-step reactions.
