This invention relates generally to the synthesis of E-macrocycles using stereoretentive ruthenium olefin metathesis catalysts supported by dithioiate ligands. Macrocycles were generated with excellent selectivity (>99% E) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield) from diene starting materials bearing two E-olefins or bearing one E-olefin and one terminal olefin, A variety of rings were constructed, ranging from 12- to 18-membered macrocycles, including the antibiotic recifeiolide. The invention has utility in the fields of organometallics and organic synthesis.

A process of obtaining a purified geometric isomer of an unsaturated macrocyclic compound is disclosed herein. The process is effected by contacting an ion exchange medium comprising silver ions with a mixture comprising at least one geometric isomer of the unsaturated macrocyclic compound, to thereby obtain at least one fraction comprising the purified geometric isomer of the macrocyclic compound. A system configured for performing the process is also disclosed.
