4-ETHOXY-4-OXOBUTYLZINC BROMIDE Chemical Properties,Usage,Production

Uses

4-Ethoxy-4-oxobutylzinc bromide can be used:

• As an intermediate in one of the key synthetic steps for the preparation of acrylic acid derivatives as EP3 receptor antagonists.
• As an intermediate in the final step of the total synthesis of a natural product mucosin.
• As a substrate in the synthesis of multi-substituted haloalkenes by reacting with 1-haloalkenes via Negishi cross-coupling reaction.
