CYCLISATION DE COMPOSES ETHYLENIQUES PAR ASSISTANCE D'IONS SELENIRANIUMS
Rouessac, Francis,Zamarlik, Henri
, p. 2643 - 2646 (2007/10/02)
Acid-catalyzed cyclization of ethylenic selenolactone 3 derived from homogeranic acid 1 affords one bicyclic lactone 5.This intramolecular rearrangement is induced by a seleniranium ion.
