## Abstract Both the enantiomers of rhynchophorol [(__E__)‐6‐methyl‐2‐hepten‐4‐ol (1)], the male‐produced aggregation pheromone of the American palm weevil (__Rhynchophorus palmarum__), have been synthesized by reducing their precursors, (__R__)‐ and (__S__)‐6‐methyl‐2‐heptyn‐4‐ol (2), which have b
