Abstract

The esters R[C[triple bond, length half m-dash]C]2·CH2CH[graphics omitted]CH·[CH2]7·CO2Me{R = Me[CH2]2, MeC[triple bond, length half m-dash]C, cis- or trans-MeCH[double bond, length half m-dash]CH, trans-HO·CH2·CH[double bond, length half m-dash]CH, HO·CH2·C[triple bond, length half m-dash]C, cis- or trans-MeO2C·CH[double bond, length half m-dash]CH, MeO2C·C[triple bond, length half m-dash]C, (EtO)2CH, OHC, or, H2N·OC} were prepared from the Wittig salt Me3Si·C[triple bond, length half m-dash]C·CH2·CH2·PPh3I–via IC[triple bond, length half m-dash]C·CH2·CH[graphics omitted]CH·[CH2]7·CO2Me; several were specifically labelled [at C(9), C(17), and C(18)]. The Wittig salt offers a general route to 1-ene-4,6-diyne and more highly unsaturated skipped en-yne systems.
