A short synthesis of (+/-)-spectinabilin via a trans-selective Suzuki coupling and subsequent Negishi-type methylation, and its biomirnetic conversion to (+/-)-SNF4435C and, (+/-)-SNF4435D is described.

(±)-N-acetyl-aureothamine (4) and (±)-spectinabilin (5) are presented. The key steps in the synthesis of (±)-3, (±)-4 and (±)-5 are the construction of the tetrahydrofuran motif using a palladium-catalyzed cycloaddition and the ruthenium-catalyzed cross metathesis of alkene 17 to form the common intermediate, boronic ester 24, which was further transformed using a trans-selective Suzuki coupling with a
