beta-Nitroacrylates and silyl enol ethers as key starting materials for the synthesis of polyfunctionalized beta-nitro esters and 1,2-oxazine-2-oxides

摘要

The reaction of silyl enol ethers with beta-nitroacrylates, in the presence of tetrabutyl ammonium fluoride as catalyst, allows the formation of polyfunctionalized beta-nitro esters, or hexahydro-4H-benzoxazine-2-oxides, depending on the nature of the starting silyl enol ethers.
