Functionalized chiral γ-butyrolactones as C5 building units: A straightforward formal synthesis of (+)-exo- and (+)-endo-brevicomines

Article abstract of DOI:10.1016/0957-4166(96)00252-2

A straightforward formal synthesis of the insect pheromones (+)-exo-brevicomin 3 and (+)-endo-brevicomin 4 starting from homochiral functionalized γ-butyrolactones 1 and 2 as C₅ building units is presented.
