A stereoselective Lewis acid-catalyzed and chelation controlled intramolecular Diels-Alder entry into the tricyclo[9.3.1.0(3,8)]pentadecane core of aromatic C-ring taxanes is described. The approach affords an efficient, high yield, access to aromatic C-ring taxanes variably functionalized at the C2, C4, C5, and C9 positions. (C) 2003 Elsevier Science Ltd. All rights reserved.
