✦ Synopsis

Remote Substituent Effects on the Enantiomeric Excess of Intramolecular Asymmetric Palladium-Catalyzed Polyene Cyclizations. -Remote substituents show a strong influence on the enantioselectivity of the title reactions. Excellent enantioselectivity is obtained by cyclization of the O-methyl triflate (Ia). -(LAU, STEPHEN Y. W.; KEAY, BRIAN A.; Synlett (1999) 5,
