A CuI-catalyzed synthesis of 1,3-disubstituted allenes from 1-alkynes by the reaction with various N-tosylhydrazones has been developed. This method, which uses readily available starting materials and is operationally simple, offers 1,3-disubstituted all
A new method for synthesis of allenes, including an optically active form, from aldehydes and alkenyl aryl sulfoxides by sulfoxide-metal exchange as the key reaction and an application to a total synthesis of male bean weevil sex attractant

The sulfoxide-metal exchange reaction of β-acetoxy sulfoxides or β-mesyloxy sulfoxides, which were derived from alkenyl aryl sulfoxides and aldehydes in two steps, with a Grignard reagent or alkyllithium at low temperature gave allenes in good yields. Optically active allenes were synthesized starting from optically active 2-substituted ethenyl p-tolyl sulfoxides. A synthesis of (-)-methyl (E)-2,4,5-tetradecatrienoate, a male bean weevil sex attractant, was realized by this method.

Ligand exchange reaction of β-mesyloxy sulfoxides or β-acetoxy sulfoxides, which were derived from alkenyl aryl sulfoxides and aldehydes in two steps, with n-BuLi or EtMgBr at low temperature gave allenes in good yields. Optically active allenes were synthesized starting from optically active 2-phenylethenyl p-tolyl sulfoxides.
