Cycloaddition of cyclohexa-2,4-dienones with β-nitroacrylates: a short and efficient entry into bicyclo[2.2.2]octanes endowed with β-nitro-ester and β-amino ester functionality

Regio- and stereoselective cycloaddition of β-nitroacrylates with electron deficient cyclohexa-2,4-dienones leading to highly functionalised bicyclo[2.2.2]octanes having the β-nitroester group and their transformation to bicyclo[2.2.2]octanes having β-aminoester functionality is described.
