Reagent
It is a widely-used building block in organic synthesis chemistry, as it offers many different ways of molecular framework extensions. For example, it is easy in a Michael addition with nucleophiles (such as enolates or silyl enol ethers) or will be implemented in a Diels-Alder reaction with electron-rich dienes. Further it reacts with organocopper compounds from 1,4-addition (Michael addition), or with Grignard reagents 1,2-addition, ie, with attack of the nucleophile at the carbonyl carbon atom. It is used for example in multi-step synthesis in the construction of polycyclic natural products.
