The total synthesis of the C19 lipid diols 5 and 6, the enantiomers of the anthelmintic marine natural products 1 and 3, is described. Key steps in the divergent syntheses include a syn selective epoxidation of a homoallylic alcohol, a one-pot alkoxypalladation-carbonylation-lactonisation reaction sequence and a DMEAD promoted Mitsunobu inversion.

A complementary diastereoselective gold(I) or bismuth(III) catalyzed tandem hemiacetalization/dehydrative cyclization of 1,5-monoallylic diols was developed to access 1,3-dioxolanes and dioxanes. This methodology provides rapid access to protected 1,3-diols under mild conditions with high levels of diastereoselectivity.
