摘要：

(Chemical Equation Presented) A cyclophane with allene and acetylene bridges has been prepared as a single enantiomer. This acetylenic allenophane (see structure) was synthesized by a series of palladium- and copper-mediated coupling reactions. The allene bridge was derived from the ring opening of a chiral epoxy alkyne, which was prepared by a Sharpless asymmetric epoxidation of an allylic alcohol. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
