Noncyclic polyethers containing two cinnamoyl end groups have been prepared, they were cyclized by photosensitized intramolecular addition. The uptake of alkali metal (sodium and potassium) thiocyanates with these compounds and their ability to extract has been investigated before and after the cyclization.
The formation of arvltetralin derivatives in the photolysis of two trans-cinnamoyl moieties at both ends of a polyethylene glycol chain in the presence of lithium perchlorate
A straight forward photochemical route to aryltetralin derivatives 2a, b from a podand system containing a pair of trans-cinnamoyl moieties is reported.
