The THF-epoxide 8 has been prepared from benzyl (R)-(-l-glycidyl ether using a 10-step synthetic scheme in a stereocontrolled fashion. Compound 8 is a highly useful synthon for the synthesis of mono-and di-THF acetogenins. This new synthetic approach can also be applied to the generation of large ch

## Abstract The monomeric unit of the macrodiolide SCH 351448 has been synthesized from three building blocks. Strategic disconnections were chosen between C21–C22 (Wittig) and C10–C11 (stereoselective aldol). The __cis__ configuration of both 2,6‐disubstituted tetrahydropyran rings was established
