The asymmetricsyntheses of the C-1 sidechains of zaragozic acid A and C are described. Aldol reaction defines the chirality at C-4′and C-5′in two independent routes. Multigram preparation as well as a route amenable to derivatization are highlights of these approaches.

Despite the prevalence of repeating subunits in chiral natural products, stereocontrolled oligomerization is a largely unexplored strategy for construction of carbon skeletal frameworks. This report describes the use of silyl glyoxylates as dipolar glycolic acid synthons in a controlled oligomerization reaction for the efficient construction of the squalene synthase inhibitor zaragozic acid C.
