An attractive intermediate in the total synthesis of the eleutherobin core has been obtained. Both syn and anti aldol diastereoisomers were synthesized by two different diastereoselective reaction sequences from 5-methyl-4-(pyrrolydin-1'-yl)-5H-furan-2-one. Each diastereoisomer was esterified and subjected to an intramolecular Diels-Alder reaction, which led to an intermediate that possesses rings A and C of the eleutherobin skeleton.

Abstract
An attractive intermediate in the total synthesis of the eleutherobin core has been obtained. Both syn and anti aldol diastereoisomers were synthesized by two different diastereoselective reaction sequences from 5-methyl-4-(pyrrolydin-1'-yl)-5H-furan-2-one. Each diastereoisomer was esterified and subjected to an intramolecular Diels-Alder reaction, which led to an intermediate that possesses rings A and C of the eleutherobin skeleton.File in questo prodotto:
