Abstract

Cyclohexane-1,3-dione derivatives synthesis from unreactive acetone has been accomplished through a consecutive Michael-Claisen process. Furthermore, the scope of different carbonyl compounds was investigated and resulted with similar consecutive Michael-Claisen process for CDD synthesis. The reaction exhibited remarkable regioselectivity in Michael addition followed by Claisen cyclization.
