Abstract
The tide compound and its C4-pivaloyloxy methyl (POM) ester have been synthesized by converting zaragozic acid A to the kev intermediate of the protected C3-hydroxymethyl compound 6. Subsequent radical deoxygen ation via the Barton-McCombie procedure, followed by deprotection, aff orded the product 11 (L-703,370). This compound possesses squalene bio synthesis inhibitory potency of 22% at 24 mpk and its C4-POM ester, 12 (L-735,142), exhibits an ED50 of 1.6 mpk in our oral mouse assay.
