β¦ Synopsis
A highly efficient synthetic method for the trans/threo/transbis-tetrahydrofuran (TI-IF) ring building block was established. The title compound was synthesized in thirteen steps from trans-l,4-dichloro-2-butene via a convergent route with a Wittig reaction as the key step. The absolute configuration of the THF segment of naturally occurring asimiiobin should be corrected.

Asymmetric synthesis of putaminoxin, a phytotoxic macrolide from the cultured dinoflagellate Amphidinium sp., has been accomplished. Absolute configuration of putaminoxin was concluded to be 1 from comparison of the NMR data and [a] D values of synthetic and natural putaminoxin.
