Benzylic, allylic, propargylic and unactivated alcohols can be oxidised with activated manganese dioxide in the presence of N-methoxy-N-methyl-2-(triphenylphosphoranylidine) acetamide to generate directly the corresponding α, β-unsaturated Weinreb amides. Elaboration of the resulting Weinreb amides is also described, in particular as part of a new route to analogues of the arachidonic acid metabolite 5-oxo-6E, 8Z, 11Z, 14Z- ...
