Kroutil, Wolfgang,Osprian, Ingrid,Mischitz, Martin,Faber, Kurt

, p. 156 - 158 (1997)

The pheromone (S)-(-)-frontalin (1) was synthesized in five steps in 94percent ee via a chemoenzymatic route. In the key step, 2-methyl-2-(pent-4-enyl)oxirane [(±)-7a] was resolved employing lyophilized cells of Rhodococcus equi IFO 3730 (E = 39).
