Diels-Alder reactions of masked o-benzoquinones with electron-rich dienophiles. Highly regio- and stereoselective synthesis of bicyclo [2.2.2]octenone derivatives

摘要

Highly regio- and stereoselective Diels-Alder reactions of masked o-benzoquinones with electron-rich dienophiles such as benzyl vinyl ether, dihydrofuran, phenyl vinyl sulfide and styrene that provide easy access to bicyclo[2.2.2]octenones are described. [References: 28]
