Asymmetric Synthesis of the C(18)-C(24) Unit of Lasonolide A. -The synthesis of the title compound (VIII) proceeds with high chiral efficiency. In six steps, four chiral centers are assembled. A key step is the modified Simpkins-Koga asym. deprotonation of compound (I). The strategy outlined is vers
