A versatile and chemoselective route to exo-methylene butyrolactones was developed by employing a three step reaction sequence consisting of Michael addition of primary nitroalkanes to ethyl (2-bromomethyl)acrylate, then Nef conversion of the nitro derivatives and subsequent lactonization of the obtaines keto esters.

A versatile and chemoselective route to exo-methylene butyrolactones was developed by employing a three step reaction sequence consisting of Michael addition of primary nitroalkanes to ethyl (2-bromomethyl)acrylate, then Nef conversion of the nitro derivatives and subsequent lactonization of the obtaines keto esters.File in questo prodotto:
