An unusual oxidative cyclization of a N-hydroxy pyridone 9 with Z-2-cyclodecenone 11 has been achieved, thus demonstrating a possible biomimetic route to pyridomacrolidin 2. [reaction: see text]

A possible biomimetic synthesis of pyridomacrolidin has been proposed and experimentally supported by carrying out a modelstudy. Regio and stereospecific [3+2] cycloaddition of an in situ generated unusual di-tert-butylated acyl nitrone with Z-2-cyclodecenone and subsequent aromatisation was the key step in our proposed biomimetic synthesis. Finally a pyridomacrolidin analogue was prepared via Friedel–Crafts
