✦ Synopsis

Abstract

The total synthesis of phytotoxic nonenolide herbarumin II (1) has been achieved by implementation of butane diacetal (BDA)‐desymmetrised glycolate building blocks. Three of the four stereogenic centres present in the key coupling fragments were generated from both enantiomeric forms of the BDA building block in highly diastereoselective alkylation and aldol reactions.

The concentration of free substrate in the filtrate was quantified by ICP-MS and the bound fraction was calculated as % bound ([total]-[free])/[total]. The proton T
