The absolutestereochemistry of (-)-galbonolide A (1) was assigned by chemical methods. First, 1 was degraded to diol 3. After selective silylation of the primary alcohol, two independent methods were carried out to determine the chirality at C13. Both established its S-configuration. Using the methodology developed in the total synthesis of (-)-galbonolide B, diols 13(S,S) and 13(S,R) were prepared
