Suppose we have a chemical compound like ethyl 4-oxo-2-cyclopentene-1-carboxylate
It is $\ce{-COOC2H5}$ bonded to a five-membered carbon ring with one double bond and the ring has another carbonyl group.
Suppose this compound is made to react with these reducing agents:
- $\ce{NaBH4}$
- $\ce{LiAlH4}$ and $\ce{H+}$
- $\ce{BH3}$, $\ce{THF}$, and $\ce{H+}$
- $\ce{H2/Pt}$
- $\ce{H2/Pd-C}$
Then what will be the product in each cases?
I know some of the reducing agents and I want to know their reactions with a compound which is unsaturated and has an ester functionality $\ce{-COOR}$ and a carbonyl group $\ce{R2C=O}$ bonded to it.
I cannot try to understand it due to my limited knowledge in chemical mechanisms.
