Abstract
Alkylidene Meldrum's acid easily reacted with silyl enol ethers withou t any catalyst to afford hetero Diels-Alder adducts which could be qua ntitatively hydrolyzed to obtain Michael adducts in good yields. The M ichael adducts could be obtained diastereoselectively and could be con verted to corresponding delta-ketoesters quantitatively.
