A multicomponent coupling strategy suitable for the synthesis of the triene component of the oxazolomycin antibioticsThis is one of a number of contributions from the current members of the Dyson Perrins Laboratory to mark the end of almost 90 years of organic chemistry research in that building, as all its current academic staff move across South Parks Road to a new purpose-built laboratory.

Concise and versatile routes suitable for the synthesis of three geometric isomers of an analogue of the left hand triene sub-unit of oxazolomycin are reported. A strategy based upon a key Heck reaction was unsuccessful, and this was traced to a combination of steric encumbrance and electronic deactivation of the alkene substrate. An alternative Stille coupling strategy, however, proved to be both versatile and high yielding, and is potentially applicable to the synthesis of analogues with variation both in the side-chain geometry and in the identity of the terminal aromatic or heteroaromatic residue.

A copper-catalyzedcross-coupling reaction of amino acid-derived amides and (Z)-vinyl iodide was studied to improve a key step in the synthesis of plocabulin, a novel microtubule destabilizer agent of marine origin. The study revealed a profound solvent effect with 1,2-dimethoxyethane (DME), which gave consistently high yields across a large variety of the amide and (Z)-vinyl iodide substrates. The
