A formal totalsynthesis of aspercyclide C (3) is described in which d-ribose is employed as a chiral pool material. The key step is a ring closing metathesis.

Enantiodivergent Formal Total Synthesis of Aspercyclide C from l-(+)-Tartaric Acid
The enantiodivergent formal syntheses of both enantiomers of aspercyclide C is accomplished. Starting from l-(+)-tartaric acid, the key protected allylic alcohol, (3R,4R)-4-(methoxymethoxy)non-1-en-3-ol is prepared, and is then elaborated into both enantiomers of 3-[(4-methoxybenzyl)oxy]non-1-en-4-ol via Mitsunobu inversion. Esterification with a known biaryl acid, followed by ring-closing metathesis
