Allylalumination of alkynes ( i.e . forming Negishi's ( Z )‐alkenyl dialkylalane) followed by alkenylation of epoxides provides 1,4‐disubstituted ( Z )‐3,6‐alkadienols. The alkenylation can be facilitated by the presence of a neighbouring coordinating group in the epoxides. This "one‐pot" approach has been successfully applied in the large‐scale production of C10–C15 fragment of 9,10‐didehydroepothilone D (a synthetic epothilone analog as an anti‐cancer agent in phase 2 clinical trials).
