Abstract

The first total synthesis and absolute configuration assignment of asperilactone B (I) have been accomplished. Additionally, a revision of the absolute stereochemistry of asperilactone C has been done. The first total synthesis of the opposite enantiomer of asperilactone B (ent-I) has also been achieved, as well as that of C-7 epimers of both asperilactones B (8) and C (9).
