RT journal article T1 Stereoselective Synthesis and Absolute Configuration Determination of Xylariolide A A1 Botubol Ares, José Manuel A1 Macías Sánchez, Antonio José A1 González Collado, Isidro A1 Hernández Galán, Rosario A2 Química Orgánica K1 Natural products K1 Total synthesis K1 Asymmetric synthesis K1 Configuration determination K1 Medicinal chemistry K1 Lactones AB The asymmetric synthesis of the antibacterial and antitumoral natural compound xylariolide A (1) and five stereoisomers has been achieved. The strategy is based on the onepot epoxidation/lactonisation or dihydroxylation/lactonisation of the hypothetical biosynthetic intermediate xylarioic A acid (8). The absolute configuration of xylariolide A was thus determined to be 3R,4S,5R,1 R,2 R after the synthesis of 1, two epimers, i.e., 1 -epi-xylariolide A (3) and 2 -epi-xylariolide A (4), and three more diastereoisomers 5–7.
