Asymmetric synthesis and initialbiologicalstudies of two analogues of a naturally occurring chlorinated antifungal agent, atpeninA5, are described. These analogues were selected on the basis of Cl→CH3 or H3C→Cl exchanges in the side‐chain of atpeninA5. The interchange of chloro and methylsubstituents led to complex II inhibitors with equal IC50 values. This suggests that Cl↔Me bioisosteric exchange
