title: Synthetic examination of incorrectly proposed structures of biomolecules.
abstract: Many incorrect structures of biomolecules have been proposed for natural products. Synthesis of compounds having the proposed structures often enabled us to judge the correctness of the proposals. In some cases, we were able to revise the structures by synthesizing the biomolecules themselves. In other cases, we were able to definitely disprove the proposed structures. Some examples treated in this review include: auxin-a and b; the sex pheromone of Chlamydomonas; sex pheromones of the gypsy moth, the American cockroach, and the pink bollworm moth; Persoons' periplanone-A; orobanchol; naurol A; bifurcarenone; koninginin A; alpha-acoradiene; himachalene-type pheromones of the flea beetle; differolide; blattellastanoside A and B; etc.
