摘要
The regioselective 1,6-conjugate addition of ethyl malonate and malononitrile to (E)-2-styrylchromones is described. A synthesis of novel pentasubstituted spirocyclohexanes discovered during the course of these studies is also discussed. A novel domino multicomponent 1,6-/1,6-/1,4-conjugate addition reaction for the formation of these new spirocyclohexanes is proposed.
