Аннотация:An effective synthetic approach to the preparation of a new crown-ether vinylogs involving the Horner-Emmons olefination of carbonyl precursors with the use of C-2- and C-5-phosphonates was proposed. The effects of the conjugation chain length and the nature of the terminal polar functions in the phosphonate reagent on the yield and process stereoselectivity were discussed.
