Description and Uses
- Ethyl 2-methylacetoacetate is used as a substrate in the rhenium-catalyzed synthesis of multisubstituted aromatic compounds.
- It can be employed in the synthesis of coumarin derivatives via Pechmann condensation.
- It undergoes dehydration to yield conjugated alkynyl and allenyl esters.
- It is also used in the total synthesis of chlorotonil A, yangjinhualine A, (+)- and (?)-saudin.
