Question

When a 1:1 mixture of ethyl propanoate and ethyl butanoate is treated with sodium ethoxide, four Claisen condensation products are possible. Draw the structure(s) of the product(s) that have an ethyl group on the chiral center

Answer 1

Answer:

attached below

Explanation:

The Four Claisen condensation are grouped into :

• Self Claisen condensation reaction
• Cross Claisen condensation reaction

Self Claisen condensation is when R = R'

Cross Claisen condensation is when R ≠ R'

attached below are the four Claisen condensation
