1-Bromo- and 1-iodo-1-alkynes are alkylated by organocopper(I) compounds. Alkenylcopper(I) derivatives undergo substitution with retention of configuration leading to conjugated and functional enynes, from which conjugated dienes can be obtained.

A general methodology for the synthesis of various types of dienic insect sexpheromones (Z-E, E-Z, Z-Z) is based on the carbocupration of acetylene by functionalised or non-functionalised lithium dialkyl cuprates, followed by the coupling of the resulting Z dialkenyl cuprates with functionalised or non-functionalised E or Z alkenyl iodides under Pd° catalysis. The following compounds were efficiently

A straightforward strategy for the synthesis of (+)-pinellic acid in 16% overall yield and 13 steps, starting from (1R)-1-(furan-2-yl)hexan-1-ol, is described. Key reactions in the synthesis include a Sharpless kinetic resolution, oxidation of a protected furan to reveal a but-2-ene-1,4-dione moiety, and an asymmetric reduction.
